Bridge Demolition Continues the Rest of the Week at I-25 and Alameda Avenue

November 1, 2010 - Denver Metro Colorado/CDOT Region 6 - DENVER — The Colorado Department of Transportation (CDOT) will continue demolishing the center portion of the Alameda Avenue bridge over I-25 tonight, November 1st through Thursday, November 4th.

The work will require full closures of northbound and southbound I-25 near Alameda Avenue tonight and tomorrow night and triple lane closures Wednesday and Thursday, weather permitting.

Tonight and tomorrow night, there will be single lane closures on northbound and southbound I-25 near Alameda Avenue starting at 8 p.m. with a second lane closing at 9 p.m. and all lanes closing at 11 p.m.  On Wednesday and Thursday, there will be single lane closures on northbound and southbound I-25 near Alameda Avenue starting at 8 p.m. with a second lane closing at 9 p.m. and a third lane closing at 11 p.m.

Each night, northbound I-25 will be closed at Broadway and southbound I-25 will be closed at Alameda Avenue.  All lanes of northbound and southbound I-25 will reopen by 5:30 a.m. the following morning.

  • Northbound Detour Route: Motorists on northbound I-25 will exit onto Broadway and take Lincoln Street north to 6th Avenue where access to northbound I-25 is available.
  • Southbound Detour Route:  Motorists on southbound I-25 will use the on and off-ramps at Alameda Avenue as a detour route; however, this will reduce I-25 to one lane and major delays are expected.  Suggested Detour Route: Due to the extensive backups predicted on southbound I-25, CDOT strongly encourages motorists exit onto 6th Avenue where they can take Broadway to I-25 or Federal Boulevard south to Mississippi Avenue and then Mississippi Avenue east to Broadway where access to southbound I-25 is available.

In addition to the lane closures on I-25, a single lane of westbound Alameda Avenue over I-25 will be closed from 7 p.m. to 5:30 a.m. on Wednesday and Thursday.

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 For a list of CDOT’s Recovery Act projects, visit
