I-25 and Santa Fe Drive

This $24 million project began in June 2014 and is scheduled for completion in late 2016. This is the third phase of improvements in this area. Phases 1.2 and 1.3 were combined as a bridge replacement project that replaced the structures on I-25 over Santa Fe Drive. 

The next phase, known as 1.4 will focus primarily on Santa Fe, Alameda and southbound Kalamath. This project is putting in a single point urban interchange at Santa Fe and I-25 and will make this area similar to University where one light controls all movements.

Phase 1.4 also constructs a bridge over the South Platte River that will carry 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.

Traffic Impacts

9 a.m. - 3 p.m. Thursday May 19
The right lane will also be closed on westbound Alameda from S. Cherokee to I-25. These lane closures are required to prepare for the weekend work on Alameda Avenue.

9 p.m. Friday, May 20 to 5 a.m. Monday, May 23
One eastbound and one westbound lane on Alameda Avenue will be closed from S. Cherokee St to I-25 for median work. One lane will remain open in each direction. Motorists should expect delays when driving through the area. This closure will accommodate the installation of new detour asphalt.

Eastbound and westbound Alameda Avenue will be reduced to one lane at South Kalamath Street. Significant utility work is required at the intersection. All motorists are encouraged to take an alternate route. A full closure of Santa Fe and Alameda may be required for installation and reconstruction of a waterline.

Late 2016:
Ramp metering will be functional. 

I25 Alameda/SantaFe Completion

April 2016: Beginning April 11 at 9 a.m. and lasting through April 27, the City and County of Denver will shut down Mississippi Avenue from Santa Fe Drive to South Broadway for a waterline installation and paving work. There will be signed detours in place. For eastbound traffic, the detour route will be Platte River Drive, to W. Iowa Avenue, to Broadway. For westbound traffic, the detour route will be Broadway, to W. Iowa Avenue, to Santa Fe Avenue. Mississippi Avenue will reopen on April 28 at 9 a.m.

Mid-March 2016: Access to southbound I-25 will be restricted for northbound Santa Fe drivers until late spring or early summer. To detour around this closure, take eastbound Alameda to southbound Broadway to access the on-ramp to southbound I-25. A number of lane shifts will also take place on Alameda and Santa Fe.
