Bridge Deck Pour To Close I-25 At Alameda Tonight

December 14, 2010 - Denver Metro Colorado/CDOT Region 6 - DENVER —Tonight, December 14th, the Colorado Department of Transportation (CDOT) will pour the bridge deck for the middle portion of the new Alameda Avenue bridge over I-25.

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

“This work was originally scheduled for later in the week, but we moved it up to take advantage of the good weather before cold temperatures return,” said CDOT Project Engineer Terrie McKinney.  “The deck pour will take one night to complete and this will be the last major construction activity until after the holidays.”

To complete the work, one lane of northbound and southbound I-25 near Alameda Avenue will be closed starting at 8 p.m. with a second lane closing at 9 p.m.  All lanes of northbound and southbound I-25 will close at 11 p.m. and will reopen at 5:30 a.m. on Wednesday.

While the full closures of northbound and southbound I-25 near Alameda Avenue are in place, motorists can utilize the following detour routes:

  • Northbound Detour Route: 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 make a left for access to northbound I-25.
  • 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 near 6th Avenue 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.

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.

To date, crews have completed construction of the northern third of the new Alameda Avenue bridge over I-25 and construction of the middle third is underway.  Once the middle third of the new bridge is complete, construction will begin on the final phase, which constructs the southern portion of the bridge.

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 contractor 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.
