Bridge Work to Close I-25 Near Alameda Avenue Tonight and Tomorrow Night

February 23, 2011 - TRAFFIC ADVISORY UPDATE - Denver Metro Colorado/CDOT Region 6 - DENVER —This week, the Colorado Department of Transportation (CDOT) has been pouring caissons for a portion of the new Alameda Avenue bridge over I-25.

To complete the work, there have been various full closures of northbound and southbound I-25 at Alameda Avenue.  This work will continue tonight, February 23rd and Thursday, February 24th with full closures of northbound and southbound I-25 each night.

To complete the work, one lane of northbound and southbound I-25 will be closed starting at 8 p.m. with a second lane closing at 9 p.m.  A full closure of northbound and southbound I-25 will begin at 11 p.m. with all lanes reopening by 5:30 a.m. the following day.  Below are the detour routes:

  • Southbound I-25 Detour: Motorists on southbound I-25 will use the on and off-ramps at Alameda Avenue. This will reduce I-25 to one lane near 6th Avenue so alternate routes are advised.
  • Northbound I-25 Detour: Motorists on northbound I-25 will exit onto Alameda Avenue and follow the detour signs to Santa Fe Drive. Once on Santa Fe Drive, head north to Cedar Avenue and take a left for access to northbound I-25.

Major delays are expected on I-25 and Alameda Avenue both nights 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.” Most fines for infractions that occur in the work zone will be doubled.

This work is part of a $37.4 million American Recovery and Reinvestment Act (ARRA) project that will replace the Alameda Avenue bridge over I-25 with one that is wider to accommodate an additional lane in each direction.  The project will also construct a longer acceleration ramp from to Kalamath Street to northbound I-25, widen I-25 under Alameda Avenue for wider shoulders and improve drainage to alleviate the flooding that often occurs in the area.

Jalisco International, Inc. of Commerce City, CO is the contactor for this project scheduled to be complete by the end of September 2012.

In all, Colorado will receive nearly $400 million from the Recovery Act for highway projects and $121 million for transit projects.  For more information about how Colorado is putting the recovery act to work, visit www.colorado.gov/recovery.
