Demolition of Bridge Over I-25 Extended Into Next Week

March 19, 2014 - Metro Denver Colorado/CDOT Region 1 - As part of the US 6 Bridges Design Build Project, crews have been working nightly to demolish portions of the bridge deck over I-25 as part of the ongoing construction.

The demolition work, originally scheduled to be complete Thursday, March 20 has been extended through at least Tuesday, March 25. Demolition work will not take place Saturday, March 22 but the closure will be implemented Sunday, March 23, through Tuesday, March 25. If necessary, crews may also utilize the closure on Wednesday, March 26 in order to complete this work. Motorists planning to drive on I-25 near the 6th Avenue interchange during these closures should expect heavy traffic and travel delays.

Crews are working to demolish the east portion of the US 6 bridge deck that crosses over I-25. Beginning at 8 p.m. each of these nights, double lane closures will be in effect on both the northbound and southbound lanes of I-25. Motorists traveling in the area should anticipate heavy delays and increased traffic in the area each night. To ensure the traveling public’s safety, 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. Traffic will be detoured starting at 10 p.m.

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.

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.
