Nightly I-25 Closures This Week

Work Continues On New Alameda Bridge Over I-25

This week, the Colorado Department of Transportation (CDOT) will be working on bridge abutments and installing bridge girders for the new northern third of the Alameda Avenue bridge over I-25. To complete the work, there will be various full closures of northbound and southbound I-25 near Alameda Avenue each night this week through Friday, July 30th.

The following closures will be in place each night, weather permitting:

Monday, July 26th: A single lane of northbound and southbound I-25 will be closed near Alameda Avenue starting at 9 p.m. with all lanes closing at 11 p.m. All lanes of northbound and southbound I-25 will reopen by 5:30 a.m. on Tuesday.

Tuesday, July 27th: A single lane of northbound I-25 near Alameda Avenue will be closed starting at 9 p.m. with all lanes closing at 11 p.m. All lanes of northbound I-25 will reopen by 5:30 a.m. on Wednesday.

Wednesday, July 28th: A single lane of northbound and southbound I-25 will be closed near Alameda Avenue starting at 9 p.m. with all lanes closing at 11 p.m. All lanes of northbound and southbound I-25 will reopen by 5:30 a.m. on Thursday.

Thursday, July 29th: A single lane of northbound and southbound I-25 will be closed near Alameda Avenue starting at 9 p.m. with all lanes closing at 11 p.m. All lanes of northbound and southbound I-25 will reopen by 5:30 a.m. on Friday.

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 take 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.

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.

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.

Drivers are also reminded that Alameda Avenue is in a temporary alignment to accommodate the bridge reconstruction. As a result, left turns are prohibited on westbound Alameda Avenue at Kalamath Street/Santa Fe Drive and at South Platte River Drive. Kalamath Street/Santa Fe Drive

Detour: Motorists needing access to southbound Kalamath Street/Santa Fe Drive from westbound Alameda Avenue can take Santa Fe Drive north to Cedar Avenue and take a left. Take Cedar Avenue west to Kalamath Street and turn left. South Platte River Drive Detour: Motorists needing access to South Platte River Drive from westbound Alameda Avenue can take a right on Lipan Avenue and take Lipan Avenue north to South Platte River Drive.

In addition, the left turns will be reduced on eastbound Alameda Avenue between Lipan Street and Kalamath Street/Santa Fe Drive. A new crosswalk is also in place at the Kalamath Street/Santa Fe Drive intersection so motorists should approach the intersection with caution.

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.
