Damage Description

CDOT is moving forward on rapid repairs to CO 7 between Lyons and Raymond on the way to Estes Park. Damage sustained during the flooding includes areas where the roadway is completely washed out, heavy debris is on and surrounding the highway, and there is damage to embankment and culverts.

Repairs Underway
Construction is underway between mile post (MP) 19, on the west end of the project, and MP 32 on the east end, and is approximately 66% complete. On Wednesday, Nov. 13, the soft closure at the east end was moved approximately one mile west from Old Saint Vrain Road, providing unrestricted access to Boulder County's Hall Ranch Open Space.

Crews have made significant progress in moving the river back to its pre-flood location, re-establishing roadway embankment, hillside stabilization, which includes rock scaling, and repairing or replacing drainage pipes or culverts.

Work has turned to completing embankment improvements and other earthwork, and constructing the new asphalt roadway surface in preparation for the Dec. 1 opening. In the meantime, teams of engineers are evaluating the roadway for safety issues and determining where barriers, signs and guardrail need to be installed.

The flood has significantly changed the roadway configuration in some parts of the canyon, and as reconstruction of the road continues, the project team is working to determine what speeds to post in the various new sections of the road to maintain safety standards. Once the speed limits are determined, signs will be ordered and installed.

The public is advised that the river next to the highway looks different compared with how it was prior to the flood due to the volume of large rocks and debris that were carried down during the event. Throughout the project, additional crews, including surveyors and hydrologists, are working to evaluate damage and identify solutions for major construction and drainage issues caused by the flooding.

Access for Residents
Local residents who can show proof of residence will be allowed between Boulder County's Hall Ranch Open Space and MP 23.5 and also between MP 29.2 and MP 33.

Residents needing access to their properties can contact the Public Information Team for arrangements. No motorists, pedestrians, or cyclists are allowed between MP 23.5 and MP 29.2, as the area in unsafe for travel of any kind. CO 7 is not open to through traffic. Ongoing construction activities may cause short delays, and travelers are encouraged to obey all traffic signs and flaggers. Barriers will remain in place until crews evaluate and address rockfall issues, clean debris, and reconstruct the roadway to make it safe for travel.

Project Information

This Permanent Repair project on CO 39 and CO 71 removed and replaced damaged roadway with riprap slope protection and completed installation of a new CBC in Morgan County.

Please find the attached 4/19/2015 weekly project update for the CO 39 and CO 71 Project.

Damage Overview

CO 39 in Morgan County, Colorado provides direct access between I-76 and the town of Wiggins, north to the town of Goodrich.  Two miles north of Goodrich is Jackson Lake State Park, accessible indirectly via CO 39/CO 144.  CO 39 sustained minor damage at three locations within the South Platte River floodplain between mileposts 6.8 and 7.5, affecting two bridges and the town of Goodrich.  Flood waters exceeded the banks of the South Platte River eventually rising enough to overtop the roadway, which weakened the pavement.  On the south end of the Town of Goodrich, the roadway was washed out across a width of 200-250 feet.

Emergency (Temporary) Repairs

The damaged roadway, shoulders and embankment were repaired as well as overhead and underground utilities.

Permanent (Long-Term) Repairs

Long-term repairs include removal and replacement of pavement that was overtopped by flood waters, repair of damaged utilities, removing and replacing temporary pavement installed during Emergency Repair and repairing and/or replacing damaged Right-of-Way fencing.  Ground adjacent to the roadway that was disturbed during Emergency Repair will be re-vegetated with native grass seed and mulch.  

Estimated Timeline

• Project is complete

Estimated Budget

• $4 to $10 million (shared with project CO 71E)

Benefits

One of the goals in the repair process was to introduce certain betterments (improvements beyond bringing the road to standard) to roadway facilities that were damaged and make them more resilient to similar storm events in the future.  Analysis of the damage caused during the flood event led to certain design elements being incorporated in an effort to prevent or lessen the severe damage that significant flood events can cause.  At this site, steps were taken to ensure the roadway has additional high water relief to handle large storm events.

Damage Overview

Colorado Highway (CO) 60 in Weld County provides an important means of access for local agricultural activities and oil and gas development. The roadway provides access from the Town of Milliken to US 85 and I-25.

During the flooding, the Town of Milliken and portions of Johnstown were completely isolated due to flood damage to CO 60 and other nearby roads. Flood waters overtopped CO 60 for about half a mile in and west of Milliken. 

The CO 60 bridge that spans the Little Thompson River experienced erosion and wash out of embankment at the abutments, loss of guardrail, and minor damage to the channel banks.  Due to the large amount of debris that collected downstream on the adjacent railroad bridge, the embankments in between the two bridges were eroded as well.

The bridge that spans the South Platte River 3 miles east of Milliken was overtopped during the flood event.  The roadway itself was also overtopped for approximately 1,000 feet on the north end of the bridge.  The north abutment of the bridge was eroded and 10 feet of roadway pavement and embankment were washed out, exposing the bridge support piles.  Large amounts of debris and sediment were deposited upstream and underneath the bridge.

Emergency (Temporary) Repairs

Temporary repairs were completed and the highway was reopened to traffic on September 21, 2013.  At both locations, the roadway around the damaged abutments was repaired.  The exposed piling and concrete abutment structures were filled and repaired. The south roadway embankment slopes and ditch were re-graded and backfilled, and guardrail was repaired or replaced.

Permanent (Long-Term) Repairs

Long-term repairs at the Little Thompson River will include removal and replacement of pavement overtopped by flood waters, repair of damaged utilities, removing and replacing temporary pavement installed during Emergency Repair and repairing and/or replacing damaged Right of Way fencing.  Embankment slopes adjacent to the roadway that were disturbed during Emergency Repair will be re-vegetated with native grass seed and mulch.  Erosion protection will be installed along the east bank of the Little Thompson River to tie into repairs made by the nearby railroad.   

No permanent repairs will be made to the bridge crossing the South Platte River as the structure has been funded for replacement.  

Estimated Timeline

• Design Start: Fall 2014
• Construction Start: Winter 2016 to 2017

Estimated Budget

• $10 to $20 million (shared with project CO 257A)

Benefits

One of the goals in the repair process is to introduce certain betterments to roadway facilities that were damaged and make them more resilient to similar storm events in the future. Having analyzed the damage caused during the flood event, certain design elements will be incorporated in an effort to prevent or lessen the severe damage that significant flood events can cause.

At the Little Thompson River bridge site, protecting the roadway embankments on both sides of the highway east of the bridge will help prevent erosion failure during similar flood events.

Project Information

This Permanent Repair project on CO 39 and CO 71 removed and replaced damaged roadway with riprap slope protection and completed installation of a new CBC in Morgan County.

Please find the attached 4/19/2015 weekly project update for the CO 39 and CO 71 Project.

Damage Overview

CO 71 in Morgan County provides direct access across the South Platte River between Synder and I-76 at Brush.  The area is largely rural and this highway serves local agriculture as a primary farm to market access road to nearby grain cooperatives and livestock exchanges.  CO 71 sustained severe damage near milepost 181.  Approximately 1,000 feet of roadway was overtopped, causing undermining of the roadway pavement and embankment.  In addition, a section of roadway at milepost 181 was completely washed out.  The bridge at milepost 181.5 that spans the main channel of the South Platte River sustained minor erosion around the piers and abutments.

Emergency (Temporary) Repairs

Remaining water from the event was pumped out or allowed to evaporate and the displaced pavement and embankment material was removed.  The roadway base and embankment were reestablished and the roadway re-paved.   A temporary culvert was also installed to alleviate pooling water.

Permanent (Long-Term) Repairs

Some of the roadway that was overtopped by floodwaters may be replaced to ensure its stability.  Additionally, the roadway and embankment placed during the Emergency Repair work will be replaced.  Damaged Right-of-Way fencing will be repaired or replaced and slopes adjacent to the roadway disturbed during Emergency Repair will be re-vegetated with native grass seed and mulch.

Estimated Timeline

• Project is complete.

Estimated Budget

• $1 to $4 million (shared with project CO 39A)

Benefits

One of the goals in the repair process was to introduce certain betterments (improvements beyond bringing the road to standard) to roadway facilities that were damaged and make them more resilient to similar storm events in the future.  Having analyzed the damage caused during the flood event, certain design elements were incorporated in an effort to prevent or lessen the severe damage that significant flood events can cause.  At this site, high-water-relief culverts were installed at the highway low point to mitigate flood waters overtopping the roadway during similar large storm events.  Additionally, embankment armoring (riprap) were installed to protect the downstream embankment from severe erosion if water overtops the roadway. 

Project Complete

Damage Overview

This section of Colorado Highway 119 provides East-West access from Boulder to Nederland.  Boulder Creek winds through the canyon adjacent to the highway.  Intense rain in the mountainous terrain surrounding CO 119 saturated the steep embankments and triggered the movement of rock, mud, and debris with the runoff down the mountain slopes and onto the highway in several locations.  The runoff flooded roadside ditches and clogged drainage culverts causing floodwater to flow over the highway and deposit debris.  There was damage to ditches, embankments, guardrails, and pavement.  The excess rainfall increased flows in Boulder Creek causing erosion and undermining of the roadway embankments and shoulders, resulting in roadway failures in several places.

Emergency (Temporary) Repairs

CDOT maintenance removed large amounts of rock debris from the highway surface and repaired numerous material slides along the canyon slopes adjacent to the highway.  Damaged embankments, ditches, culverts, and guardrail were repaired and sections of pavement loss were filled and repaved.

Permanent (Long-Term) Repairs

Permanent repairs will include removing and replacing materials placed during emergency repairs, excavating slope failures where necessary, reconstructing embankments, and reestablishing native grass seed and erosion control to slopes that were disturbed during ER work. In elongated areas with major road damage, the road width template is being analyzed to see what the cost/benefit ratio is to build a wider road.  

Estimated Timeline

• Design Start: Fall 2014
• Construction Start: Spring 2016

Estimated Budget

• $4 to $10 million

Benefits

One of the goals in the repair process is to introduce certain betterments to roadway facilities that were damaged and make them more resilient to similar storm events in the future.  Having analyzed the damage caused during the flood event, certain design elements will be incorporated in an effort to prevent or lessen the severe damage that significant flood events can cause.  Along this corridor, there are several proposed site resiliencies that will be determined during the initial design phase of the permanent repair project.

Latest Updates

On May 2, 2015, CDOT began a $12 million project along CO 119 (Diagonal Highway), just west of Longmont in Boulder County, from mile points 44.995 to 54.42, to improve the ride-ability and traffic operations for motorists.

In addition to resurfacing work, guardrails and bridge rails will be replaced, and minor bridge repairs will be performed and signs replaced along the construction zone. Motorists can expect the project to be completed by October.

During the project and construction, crews will work to minimize any traffic impacts. Lanes shifts and lane closures may occur and will be directed by flaggers at both ends of the work zone. All construction requiring lane closures will occur from 9 a.m. to 7 p.m. in the southwest direction, and from 7 a.m. to 3 p.m. in the northeast direction. Work not requiring lane closures will occur from 7 a.m. to 7 p.m. in both directions.

Damage Overview

This section of CO 119 is a major expressway providing access between Boulder and Longmont.  Several creeks and drainages flow through the area and pass under the highway.  High flows during the flood event caused varying erosion at the bridge structures, damage to drainage culverts, and damaged trail facilities near the highway.  Some channels were degraded and new flow paths were created by the floodwaters causing a buildup of sediment and debris.

Emergency (Temporary) Repairs

Minor work was done mostly by local agencies including sediment removal and repairs to the adjacent railroad grade (by the railroad line owner).

Permanent (Long-Term) Repairs

Permanent repairs will include re-stabilizing channel embankments, re-vegetation, culvert inlet/outlet protection, and repairs on localized erosion around bridge abutments and piers with additional erosion protection.

Estimated Timeline

• Design Start: Fall 2014
• Phase 1 - Structure repairs and protection to be completed by summer 2015

Estimated Budget

• $1 to $4 million

Benefits

The permanent repair phase will allow for the betterment of drainage facilities and erosion protection areas throughout the corridor that can handle the high flows from large storm events and protect facilities from potential damage in the future.

Damage Overview

CO 257 is a primary commuter access route between Greeley and the Milliken/Johnstown area, connecting CO 60 in Milliken and US 34 about 10 miles west of Greeley. During the flood event, floodwaters from the Little Thompson River overtopped the roadway in Milliken from the intersection with CO 60 north to where CO 257 crosses the main channel of the river.

The bridge there sustained significant damage to its abutments, and part of the roadway was washed out.  Farther north, where CO 257 crosses the Big Thompson River, similar damage occurred to the bridge there as more than half-of-a-mile of roadway was overtopped.

Emergency (Temporary) Repairs

Temporary repairs were completed and the highway was reopened to traffic on Sept. 29, 2013. At both locations, the roadway around the damaged abutments was repaired. The exposed piling and concrete abutment structures were filled and repaired. The roadway embankments were repaired, and damaged guardrail sections were reset. At the Little Thompson site the east roadway embankment and ditch were re-graded and repaired.

Permanent (Long-Term) Repairs

Long-term repairs will include removal and replacement of pavement overtopped by flood waters, repair of damaged utilities, removing and replacing temporary pavement installed during Emergency Repair and repairing and/or replacing damaged Right of Way fencing. Ground adjacent to the roadway that was disturbed during Emergency Repair will be re-vegetated with native grass seed and mulch.

Estimated Timeline

• Design Start: Fall 2014
• Construction Start: Winter 2015-2016

Estimated Budget

• $10 to $20 million (shared with project CO 60B)

Benefits

One of the goals in the repair process is to introduce certain betterments (improvements beyond bringing the road to standard) to roadway facilities that were damaged and make them more resilient to similar storm events in the future.  Certain design elements will be incorporated in an effort to prevent or lessen the severe damage that significant flood events can cause. At the Little Thompson River bridge site, protecting the roadway embankments on the east side of the highway will help prevent erosion failure during similar flood events.

Damage Overview

Just north of the intersection with CO 119, I-25 passes over Saint Vrain Creek.  The surrounding area and the bridge structures suffered extensive damage during the September flood event.  The floodwaters of Saint Vrain Creek joined Idaho Creek floodwaters and collectively flowed into the west side ditch along I-25.  This caused damage to the highway embankment, the existing water quality facility, and the banks that guide the water under the bridge.

Floodwaters washed out material on both sides of the creek underneath I-25.  The flows also washed out a concrete path on the south side of the creek and embankment material on both sides.  Floodwaters further caused a complete washout of the water quality pond and the pond outlet structure.

Emergency (Temporary) Repairs

There were no emergency repairs done at this site.

Permanent (Long-Term) Repairs

As part of a larger project to repair multiple bridge structures that suffered flood damage, the damaged embankment near the Northbound bridge was repaired.  Additional permanent repairs will include rebuilding the guide bank.

Estimated Timeline

• Permanent Embankment Repair Project Completed June 2014
• Design Start: Fall 2014
• Construction Start:  Winter 2015-2016

Estimated Budget

• $4 to $10 million (shared with other bridge structures)

Benefits

The permanent repair phase will allow for the betterment of drainage facilities and erosion protection areas throughout the corridor that can handle the high flows from large storm events and protect facilities from potential damage in the future.

Latest Updates

Erosion Controls of Colorado has completed most contract work. The remaining work recently completed was related to the slope stabilization of a severely eroded slope above the ground nail wall in the northwest quadrant of I-225 and Mississippi.

This slope has been stabilized via the installation of soil retention blankets, anchors and Turf Reinforcement Mat (TRM). As of June 1, 2016, approximately two days of work remains related to grading and installation of TRM on the roadway ditch. This work will be complete as soon as the respective area dries from recent rain. The only impacts to I-225 will be shoulder closures.

Damage Overview

I-225 is a six lane interstate providing major north-south access within the Denver metro area.  In many areas, the roadway is lower compared to the surrounding area, with relatively steep slopes leading away from the shoulders.  At several locations north of Mississippi Avenue on southbound I-225, the slopes became saturated from the rains, causing the soil to slide down the slopes and into the ditch below.  There were multiple areas in the section from 6^th Avenue to Smith Road where the joint filler in the concrete pavement had been pushed up and out of the joints from pressure caused by the rain.

Emergency (Temporary) Repairs

The slide material from the slopes came to rest in the ditch and was determined not to be a danger to the travelling public, so no Emergency Repair  work was performed to remove the slide material.  During water pumping operations, an erosion hole formed at the outlet of the pumping hose.  CDOT filled the hole with concrete to protect the embankment and roadway from being undermined during water removal operations.

Permanent (Long-Term) Repairs

Long-term repairs will include removal of the slide material from ditches and placing it back into the slide areas with turf reinforcement mats and seeding for new vegetation.  The expansion joints that were damaged will be cleaned out and replaced.    

Estimated Timeline

• Est. Design Start:  Summer 2014
• Est. Construction Start: Summer 2015

Estimated Budget

• $1 million

Benefits

One of the goals in the repair process is to introduce certain betterments to roadway facilities that were damaged and make them more resilient to similar storm events in the future.  Based on analysis of  the damage caused during the flood event, certain design elements will be incorporated in an effort to prevent or lessen the severe damage that significant flood events can cause.  At the I-225/I-70 flooding site, the turf reinforcement mats will improve the stability of the slope and prevent similar damage in future storm events.

Background

Starting in mid-October 2017, crews began removing and replacing bridges over the Little Thompson River on Colorado Highway 60 and Colorado Highway 257. This permanent repair work is necessary following the 2013 flood. On Monday, July 2, crews re-opened the CO 257 bridge over the Little Thompson River—about three months sooner than anticipated.

Benefits

This project will:

• Improve the quality of the highway, providing better drivability for motorists
• Ensure safe travel over bridges
• Provide resiliency to roadway and bridges to sustain future storm events
• Protect roadway embankment

Schedule

Normal working hours: 7 a.m. to 5 p.m., Monday through Saturday

Traffic Impacts

• Expect minimal traffic impacts during seeding.

Project Overview

When the September 2013 storms wiped out a large section of US 34 east of Greeley, it became clear that a better, long-term solution was needed to ensure the road could withstand a major rain event in the future.

In October 2014, construction began on a $22 million permanent fix to the road that includes a new bridge. Flatiron Constructors Inc. was selected as the contractor for the project. 

In October 2015, traffic moved onto the new bridge over the “big hole”. Although the bridge is not over an active watercourse, heavy rains in May 2015 again demonstrated that this area is subject to flooding when high water inundated the work area. Together, the bridge and new box culvert west of the US 34 / US 34 Business intersection, provide needed drainage improvements for this important transportation corridor

The project was substantially complete in December 2015.

January 2016 – All lanes are now in the final alignment. Final signing, striping and finishing work will occur throughout the month.

Damage Overview

US 34 (bypass) Southeast of Greeley, Colorado, sustained substantial damage between mile markers 114 and 116. Flood waters upstream of the highway exceeded the banks of the main channel of the South Platte River and then flowed northeast where they overtopped US 34. As a result of the water flooding over the roadway, a large section of the roadway washed out east of the highway’s intersection with US 34 (Business) and portions of the westbound lanes were undermined east and west of the intersection. Additionally, sediment and debris were deposited throughout this area.  The highway was closed for a period of 17 days before emergency repairs could be made to re-establish transportation routes.

Emergency (Temporary) Repairs

Temporary repairs were completed and the highway was reopened to limited traffic in both directions on Oct. 1, 2013.  Work involved removal of sediment and debris from roadways and ditches, repair and installation of reinforced concrete pipes, scour hole repair, repaving of the roadway and re-establishment of the embankments. At milepost 115.4 a temporary detour was constructed to route the traffic around the damaged portion of roadway often referred to as the "big hole". The temporary detour will be replaced by a bridge during the current permanent repair phase.

Project Complete

Traffic Impacts

• Normal work hours: 8:30 a.m. to 3:30 p.m., Monday through Friday
• Haul trucks will be entering/exiting the work zone and will prompt short traffic holds, if any

Damage Overview

This section of US 36 is one of the main corridors providing access between Estes Park and Boulder crossing both the St. Vrain Creek and Left Hand Creek. Floodwaters caused extensive damage to these channels as well as the structures along US 36. Damage included large amounts of debris an sediment deposit, erosion of the roadway embankment, overtopping of the roadway, scour damage of the bridge piers and abutments, and exposing underground utilities. 

Benefits

One of the goals in the repair process is to introduce certain betterments to roadway facilities that were damaged and make them more resilient to similar storm events in the future. Having analyzed the damage caused during the flood event, certain design elements will be incorporated in an effort to prevent or lessen the severe damage that significant flood events can cause. The permanent repair phase will allow for the betterment of drainage facilities and erosion protection areas throughout the corridor that can handle the high flows from large storm events and protect facilities from potential damage in the future.

About the Project

This flood project involves installing two major drainage structures under US 36 by removing the roadway surface, excavating, and drilling horizontally beneath the highway. The project is approximately eight miles south of Estes Park near the Lion Gulch trailhead. Work entails rock blasting, re-benching the embankment between the highway and the Little Thompson River, restoring the river alignment, and placing riprap along the river’s restored alignment. These permanent repairs are a follow-up to emergency repairs made after the September 2013 Flood disaster and will offer a permanent fix to meet long-term transportation safety and functional standards. These repairs will also prevent the roadway from washing out in future storms, protecting lives and minimizing the need for road closures and repairs.  

Project Purpose

This project is designed to put the Little Thompson River back into its natural alignment through Muggins Gulch and honor commitments made with the U.S. Forest Service to return the channel to its historic ecological function. When US 36 was built in 1937, the river was channeled away from Muggins Gulch into the roadside ditch that exists today. This section of the river channel washed out in the 1976 and 2013 floods, causing significant damage to the roadway embankment that resulted in costly repairs and extended closures of a primary route in and out of Estes Park and Rocky Mountain National Park. New drainage structures installed for the permanent repair will return the river to its natural path beneath the highway and minimize erosion damage and highway closures during the next flood.

Project Timeline

Initial construction work is scheduled to begin in January 2020 and the project is expected to finish in early 2021. A full closure of US 36 at Mile Point 8 was completed March 27. Refer to the Travel Impacts page for more information.
