I-70, Tower Road to Colfax Avenue

The Colorado Department of Transportation (CDOT) is reconstructing the 2 ½ mile segment of Interstate 70 between Tower Road and Colfax Avenue (U.S. 40/287). Work for this project consists of removing portions of the existing asphalt and replacing it with concrete pavement, other areas of existing asphalt will be overlaid with new concrete pavement, shoulder widening, and new bridges over the Union Pacific Railroad and Smith Road.  The project also includes numerous retaining walls, new drainage improvements and water quality ponds, guardrails, curbs and gutters, signing and striping.

The bridge demolition and reconstruction that is part of this project replaced a bridge that is at capacity. The new bridges included wider shoulder lanes that have improved safety for all motorists. 

During this phase of construction, the on ramp from northbound Tower Road to eastbound I-70 was realigned to improve the flow of traffic and safety at this location.  However, please continue to use caution in this area and be aware of surrounding traffic. Motorists traveling in this area are encouraged to allow for extra time to get to their destinations and to use caution. Phasing of this project has allowed traffic flow to continue in the area at reduced capacity without utilizing full long term complete road closures as originally designed. By removing and replacing the bridge in two segments traffic flow continued on this stretch of road with lane reductions.

Traffic Impacts

Two lanes of traffic are now open in each direction of I-70. The project is currently in a winter shutdown. During construction speed limits in the area have been reduced from 70 miles per hour to 55 miles per hour. This project is scheduled to be complete before spring, depending on weather.  For more information or questions about this project, please email or call the project team at:  or 720-583-5944.
