Demolition of bridge over I-25 requires rerouting highway traffic

March 4, 2014 - Denver Metro Colorado/CDOT Region 1 - DENVER – Sunday, March 9 through Thursday, March 13, motorists on I-25 near the 6th Avenue interchange should expect heavy traffic and travel delays. Beginning at 10 p.m. each of these nights, crews will be doing demolition work on the east portion of the US 6 bridge deck that crosses over I-25.

To ensure the safety of the traveling public, southbound I-25 will be diverted off the highway at 6th Avenue and northbound I-25 traffic will shift over into the southbound lanes to travel beneath the bridge.

Southbound I-25 motorists will be detoured west on US 6 to Federal Boulevard then south on Federal to 5th Avenue to take eastbound US 6 and reconnect with southbound I-25. With I-25 traffic making this loop detour, people traveling south on Federal Boulevard and east on US 6 can also expect heavier than normal traffic, particularly between the hours of 10 p.m. and midnight each night. To facilitate traffic movement on Federal Boulevard, the eastbound US 6 off-ramp to Federal will be closed.

Traffic in both directions of I-25 will be narrowed down to a single lane prior to reaching 6th Avenue and this process of funneling traffic into one lane will begin prior to 10 p.m. so drivers should plan for heavy traffic beginning about 9:30 p.m.

Regional northbound through traffic should avoid the area by taking C-470 or I-225 to I-70 and northbound local traffic can take Santa Fe Drive north to 8th Avenue. Regional southbound through traffic should avoid the area by taking I-70 west to C-470 or east to I-225 and southbound local traffic can use Colfax or 8th avenues.

The $98 million US 6 Bridges Design-Build Project will replace six obsolete bridges on US 6 between Knox Court and I-25, improve traffic movements in the I-25 and US 6 interchange and enhance driver safety by eliminating several traffic weave movements along US 6 between Federal Boulevard and I-25. Substantial project completion is planned for August 2015.
