I-25 and Fillmore Street Interchange

Fillmore Plan Color withURSPond Reduced Size

Overview

In February 2015, the Colorado Department of Transportation (CDOT) began an interchange reconstruction project at I-25 and Fillmore Street in El Paso County in Colorado Springs. The project will convert the existing interchange into a Diverging Diamond Interchange (DDI), the second along the Front Range and the third in the State of Colorado.

SEMA Construction Inc. is the primary construction contractor for this project, which cost $15.1 million.

Upcoming Closure

The I-25 & Fillmore Street Interchange project will be partially closed to traffic over the next two weekends for intersection construction.

From Friday, August 21, at 8 p.m. through Monday August 24, at 5 a.m., the ramps from southbound I-25 to Fillmore Street and Fillmore Street to southbound I-25 will be closed. In addition, Fillmore Street will be closed between Chestnut Street and the  orthbound I-25 ramps. All westbound Fillmore Street traffic will have to exit to northbound I-25. Northbound I-25 traffic can exit at Fillmore but will only be able to go east on Fillmore.

From Friday, August 28, at 8 p.m. through Monday August 31, at 5 a.m., ramps from northbound I-25 to Fillmore Street and from Fillmore Street to northbound I-25 will be closed. Fillmore Street will be closed from Mark Dabling Boulevard to the I-25 southbound on- and off-ramps. The northbound on- and off-ramps will also be closed. In addition, Fillmore Street will be closed between Mark Dabling Boulevard and the southbound I-25 ramps. All eastbound Fillmore traffic west of I-25 will need exit to southbound I-25. Southbound I-25 traffic can exit at Fillmore but must go west on Fillmore.

Project Progress

To date the project is approximately 20 percent complete and on pace to conclude in summer 2016. Upcoming work will focus on constructing the northbound off-ramp, which will include some permanent paving as well as paving for a temporary ramp to get vehicles around the construction zone.

Schedule and Traffic Impacts

Normal working hours are from Monday through Friday from 7 a.m. to 5 p.m. There will be some nighttime and weekend work as needed.

The speed limit is reduced in the construction zone on I-25 to 55 mph for both the safety of the traveling public as well as construction crews working along the highway.

Business access will be maintained. Construction crews will accommodate pedestrians and bicyclists through the construction zone as much as possible. Please use caution and stay alert while traveling through the construction zone. Follow flaggers’ directions and reduced posted speed limits.

About the DDI

The Diverging Diamond Interchange transitions traffic from one side of the road to the opposite side. This innovative interchange will improve safety and traffic flow through the corridor to meet existing and future travel demands.

As part of this project, two new bridges will be constructed to replace the current bridge structure, which was built in 1960 and widened in the 1970s. Each bridge will be approximately 220 feet long, with a 14-foot-wide sidewalk on the eastbound side for pedestrian use. There also will be 5-foot-wide bicycle lanes eastbound and westbound on both bridges. In addition, the southbound off-ramp and northbound

on-ramp for I-25 will be lengthened to accommodate the amount of traffic utilizing this route.
