Lane Closures on Northbound Santa Fe at I-25

January 19, 2016 - Denver Metro/CDOT Region 1 - DENVER – Effective the morning of Monday, Jan. 25, northbound Santa Fe Drive will be reduced to a single lane of travel for several weeks beneath I-25.

While two lanes will still be maintained on the flyover ramp that takes northbound Santa Fe drivers onto northbound I-25, northbound Santa Fe Drive itself will be reduced to one lane between the on-ramp to southbound I-25 and the off-ramp from northbound I-25.

This configuration will be in place until mid-March at which time the northbound Santa Fe on-ramp to northbound I-25 will be reduced to one lane and the on-ramp to southbound I-25 will close to northbound Santa Fe drivers. By the end of April the project expects to restore the two lanes on northbound Santa Fe Drive and along the on-ramp to northbound I-25. The on-ramp to southbound I-25 will remain closed until late spring or summer. Motorists should expect delays when driving through this area.

These lane closures are necessary to keep traffic moving through the area while crews redesign the intersection into a single point urban interchange. When completed this summer, this interchange will be similar to the intersections of Santa Fe Drive and Evans Avenue and University Boulevard and I-25. A single point urban interchange features a single traffic signal that permits simultaneous left-hand turns to move cars more efficiently. When work is done, this improved intersection will facilitate left turns onto southbound Santa Fe Drive from northbound I-25.

All construction activities are weather-dependent, and the schedule is subject to change. For updated project information, visit, call 303-901-9020 or email[email protected]


This $24 million project began in June 2014 and is scheduled to complete in June 2016. Phases 1.2 and 1.3 were combined as a bridge replacement project that replaced the structures on I-25 over Santa Fe Drive. This project is now complete.

The current phase focuses primarily on Santa Fe, Alameda Avenue and southbound Kalamath and includes the new bridge over the South Platte River that now carries southbound I-25 off-ramp traffic onto southbound Santa Fe Drive. In addition, this project will widen Alameda Avenue at Santa Fe Drive/Kalamath.

This project will improve safety for the traveling public in this area and will help to reduce congestion and improve mobility in this heavily traveled section of the metro area.
