US 34 east of Greeley to have one-lane traffic Thursday through Saturday

June 23, 2015 - Northeastern Colorado/CDOT Region 4 - GREELEY – Starting on Thursday, June 25, motorists will be subject to one-lane traffic control Thursday, through Saturday, June 27 from 7 a.m. to 7 p.m.

The reduction in lanes is needed to allow crews to bring in girders for the new bridge being built as part of the permanent repairs to US 34 following the 2013 floods.

If needed, traffic will be held momentarily under flagger control to lift and place girders closest to the temporary road.

The girders, which are part of the bridge superstructure, will be delivered to the work zone beginning each morning and throughout the day for three days (Thursday, June 25 through Saturday, June 27). Each girder will be lifted and set in place by crane. The safety of the crews and motorists is extremely important. It is necessary to minimize potential conflicts between a safety-critical construction operation and the public.

Installing the bridge girders is a major milestone for the project, which is scheduled for completion in fall 2015.


Damage Overview - US 34 (bypass) Southeast of Greeley, Colorado, sustained substantial damage between mileposts 114 and 116. Flood waters upstream of the highway exceeded the banks of the main channel of the South Platte River and were directed northeast toward the damaged section where they overtopped the highway. As a result of the water flooding over the roadway, an entire 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.

Project Overview - This $22 million project will construct a new bridge where US 34 washed out. The project also includes installing a box culvert under the roadway and upgrading design elements to current CDOT standards. The horizontal alignment (i.e., curvature) of US 34 will be flattened to meet the requirements of a higher design speed.
