Bridge Demolition to Close I-25 at Alameda Avenue Next Week
The work will require full closures of northbound and southbound I-25 near Alameda Avenue on Sunday, Tuesday and Thursday and single lane closures on Monday and Wednesday.
“This is the last portion of the existing bridge that we need to demolish and reconstruct,” said CDOT Project Engineer Terrie McKinney. “To complete the work, we must completely close northbound and southbound I-25 three nights next week and possibly two more the following week. We will not have full closures on Monday and Wednesday due to sporting events downtown.”
To complete the bridge demolition, the following closures will be in place next week, weather permitting:
- Sunday, Tuesday and Thursday: 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 in place each night from 11 p.m. to 5:30 a.m.
o 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.
o 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.
- Monday and Wednesday: One lane of northbound and southbound I-25 near Alameda Avenue will be closed from 8 p.m. to 5:30 a.m.
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.
