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.
