NB Santa Fe to SB I-25 Ramp Closing this Weekend

March 10, 2016 - Denver Metro/CDOT Region 1 - DENVER – The Colorado Department of Transportation (CDOT) is closing the ramp from northbound Santa Fe Drive (U.S. 85) to southbound Interstate 25 on Saturday night to as part of the I-25/Santa Fe Drive Interchange Reconstruction Project.

It will remain closed for about two months.

Drivers wanting to access southbound I-25 from northbound Santa Fe will need to continue north on Santa Fe to Alameda Avenue, then east on Alameda to Broadway, and then south on Broadway to I-25.  Motorists should expect delays when driving through this area, especially during the morning and evening commuting hours. 

The ramp closure is scheduled to remain in place through mid-May.  Closing it allows a new storm sewer line to be installed and upgraded curbs and gutters to be constructed.  The grade of the ramp also will be increased. 

PLEASE NOTE: The ramp from northbound Santa Fe to northbound I-25 will be CLOSEDfrom 8 p.m. Saturday to 5 a.m. Sunday.  To access northbound I-25, continue north on Santa Fe to Cedar Avenue, two blocks north of Alameda.  Turn left on Cedar and go west one block to access northbound I-25. 


  • Northbound Santa Fe from Mississippi to the northbound I-25 entrance ramp: One left lane closed from 9 p.m. Friday until 8 p.m. Saturday.
  • Northbound Santa Fe from Mississippi to the northbound I-25 entrance ramp: Two right lanes closed from 8 p.m. Saturday to 5 a.m. Sunday.


This $24 million project began in June 2014 and is scheduled for completion in winter 2016/2017. Phases 1.2 and 1.3 were combined as a bridge replacement project, replacing the I-25 structures over Santa Fe Drive. That project is complete. 

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

This project will improve safety for the traveling public, help reduce congestion and improve traffic flow in this heavily traveled section of south-central Denver.
