Bridge Caisson Work Continues Next Week Requiring More Full Closures of I-25 at Alameda

February 25, 2011 - TRAFFIC ADVISORY - DENVER —Next week, February 27th through March 3rd, the Colorado Department of Transportation (CDOT) will continue to pour caissons for a portion of the new Alameda Avenue bridge over I-25.

To complete the work, there will be double lane closures as well as full closures of northbound and southbound I-25 at Alameda Avenue.

The following lane closures will be in place next week, weather permitting:

  • Sunday, February 27th: 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.  In addition, the ramp from northbound Santa Fe Drive to northbound I-25 will be completely closed starting at 7 p.m.  All lanes and the ramp will reopen by 5:30 a.m. on Monday.
  • Monday, February 28th through Thursday, March 3rd: 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.  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.  In addition, the 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.  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 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 Detour: Take Santa Fe Drive north to Cedar Avenue and take a left for access to northbound I-25.

Major delays are expected on I-25 and Alameda Avenue throughout the week 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.” Fines for most 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.
