As part of the U.S. 36 Express Lanes Project, the Colorado Department of Transportation, CDOT, began closing eastbound and westbound U.S. 36 nightly on May 27. The closure will take place for a quarter of a mile on each side of the McCaslin Boulevard bridge from 10 p.m. to 5:30 a.m. nightly until the work is complete for an estimated 12 nights.
CDOT Project Direct Mark Gosselin said it’s necessary to close US 36 to begin the demolition of the northbound section of the McCaslin Boulevard bridge. The work is part of Phase 2 of the project, which will widen the existing McCaslin Boulevard bridge to accommodate the Diverging Diamond Interchange. Traffic will be detoured at the US 36 off-ramps to McCaslin Boulevard and routed immediately back onto U.S. 36 via the on-ramps. Following this partial demolition of the McCaslin Boulevard bridge, crews will construct the abutments and build the center pier. After that, crews will set the girders and pour the concrete bridge deck. For more information about the project, visit or our mobile website at
