Girder Installation to Close Northbound I-25 and Santa Fe Drive This Weekend

November 4, 2011 - Denver Metro Colorado/CDOT Region 6 - DENVER— Starting tonight, Friday, November 4th and continuing until 5:30 a.m. on Monday, November 7th, the Colorado Department of Transportation (CDOT) will install bridge girders for the new northbound I-25 bridge over Santa Fe Drive.

As a result, there will be various full closures of northbound I-25 as well as northbound and southbound Santa Fe Drive throughout the weekend.

“We have 22 girders to install, which requires full closures for an extended period of time,” said CDOT Project Engineer Dan Housand.” In order to reduce the overall impacts to traffic, we are conducting the bulk of work that affects northbound I-25 in the overnight hours and the rest of the work will be complete before the Monday morning commute.”

To complete the work, the following closures will be in place:

  • Northbound I-25 near Santa Fe Drive: All lanes of northbound I-25 will be closed near Santa Fe Drive from 10 p.m. Friday until 2 a.m. on Saturday. Detour: Motorists on northbound I-25 will take the Santa Fe Drive/Alameda Avenue exit and continue past Alameda Avenue to Cedar Avenue where access to northbound I-25 is available.
  • Northbound Santa Fe Drive under I-25: All lanes of northbound Santa Fe Drive under I-25 will be closed from 10 p.m. Friday until 5:30 a.m. Monday. Detour: Motorists on northbound Santa Fe Drive will be directed to Mississippi Avenue where they will travel east to Broadway. Take Broadway north to northbound I-25. Motorists will then need to exit off of northbound I-25 at the Santa Fe Drive/Alameda Avenue exit. After 2 a.m. on Saturday, the ramp from northbound Santa Fe Drive to northbound I-25 will reopen.
  • Southbound Santa Fe Drive under I-25: All lanes of southbound Santa Fe Drive under I-25 will be closed from 10 p.m. Friday until 5:30 a.m. Monday.  Detour: Motorists on southbound Santa Fe Drive will take Alameda Avenue east to Broadway and then take Broadway south to Mississippi Avenue. Once on Mississippi Avenue, travel west to Santa Fe Drive. There will also be detour signs to local businesses on Santa Fe Drive and Alameda Avenue.

Major delays are expected throughout the weekend and alternate routes are strongly advised. CDOT would like to remind motorists to obey all construction signs and flaggers and to “Slow for the Cone Zone.”

This work is part of the I-25/Santa Fe Drive improvement project. The $32.1 million project will conduct the following improvements:

  • Replace the existing I-25 bridges over Santa Fe Drive that are currently in poor condition. Both bridges were originally constructed in 1958.
  • Construct a flyover ramp from northbound Santa Fe Drive to northbound I-25, eliminating the left side on-ramp and improving operations and safety for this major traffic movement.
  • Reconstruct and realign I-25 from the north end of the Broadway viaduct to just south of Alameda Avenue to provide lane continuity. Once complete, there will be four lanes on I-25 in each direction through Denver from C-470 to US 36.

Hamon Contractors, Inc. is the contractor for this project, which is being partially funded by Funding Advancement for Surface Transportation and Economic Recovery (FASTER).  FASTER is dedicated to repairing and replacing poor bridges and making safety improvements on Colorado highways. The entire project will be complete by the end of July 2013.
