I-25 and Santa Fe Drive

Project Facts

  • Cost: $24 million

Project Team

  • Contractor(s): Hamon Contractors, Inc.

This project began in June 2014 and is scheduled for completion in spring 2017. 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.

In phase 1.4, crews also will construct a bridge over the South Platte River to 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.
  • Improve safety for the traveling public in this area.
  • Help to reduce congestion and improve mobility in this heavily traveled section of the metro area.

Traffic Impacts

From 9 p.m. on Friday, Dec. 2 to midnight on Monday, Dec. 5, westbound Alameda Avenue will be closed between Santa Fe Drive and Cherokee Street to accommodate paving operations on Alameda Avenue and Santa Fe Drive.

Detour: Take Cherokee Street north to Bayaud Avenue, west to Santa Fe, north to Ellsworth, west to Kalamath Street, and south to rejoin with Alameda Avenue.

Other Delays: Northbound Santa Fe Drive will be reduced to one lane during this time to accommodate paving operations at Alameda Avenue. Expect delays when driving through the area; alternate routes are advised.

Late 2016: Ramp metering will be functional.

Spring 2017: Expected completion date

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.
