Bridge Work to Close Northbound and Southbound I-25 Near Alameda Avenue Tonight With Additional Closures Later in the Week

March 15, 2011 - TRAFFIC ADVISORY UPDATE - Denver Metro Colorado/CDOT Region 6 - DENVER - This week, March 15th through March 17th, the Colorado Department of Transportation (CDOT) will continue construction of the bridge caissons for a portion of the new Alameda Avenue bridge over I-25.

To complete the work, there will be various full closures of northbound and southbound I-25 near Alameda Avenue each night.

The following closures will be in place each night, weather permitting:

  • Southbound I-25 near Alameda Avenue: Tuesday through Thursday, one lane of southbound I-25 will be closed starting at 8 p.m. with a second lane closing at 9 p.m.  A full closure of southbound I-25 will begin at 11 p.m. each night. All lanes will reopen by 5:30 a.m. the following day.  Detour: Motorists on southbound I-25 will use the on and off-ramps at Alameda Avenue.  However, alternate routes are advised.
  • Northbound I-25 near Alameda Avenue: Tuesday through Thursday, one lane of northbound I-25 will be closed starting at 8 p.m. with a second lane closing at 9 p.m.  A full closure of northbound I-25 will begin at 11 p.m. tonight only. All lanes will reopen by 5:30 a.m. the following day.  Detour: Motorists on northbound I-25 will exit onto Alameda Avenue and will 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.
  • Northbound Santa Fe Drive to Northbound I-25: Tuesday through Thursday, the on-ramp from northbound Santa Fe Drive to northbound I-25 will be completely closed each night from 7 p.m. to 5:30 a.m.  Detour: Motorists can take northbound Santa Fe Drive to Cedar Avenue and take a left for access to northbound I-25.

Major delays are expected on I-25 and Alameda Avenue 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.
