US 36 Closure Continues Through June 9 for Partial McCaslin Bridge Demolition

June 6, 2014 - Denver Metro Colorado/CDOT Region 1 - SUPERIOR/LOUISVILLE – As part of the US 36 Express Lanes Project, the Colorado Department of Transportation (CDOT) will continue to close eastbound and westbound US 36 nightly through June 9, 2014.

Nightly closures began May 27 and weather permitting will be complete in 12 nights. The closure takes place for a quarter of a mile on each side of the McCaslin Boulevard bridge from 10 p.m.-5:30 a.m.

“It’s necessary for us to close US 36 to begin the demolition of the northbound section of the McCaslin Boulevard bridge,” said CDOT Project Direct Mark Gosselin. “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 US 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.

The US 36 Express Lanes Project is a multi-modal project that will build an express lane in each direction on US 36. The lanes will accommodate High Occupancy Vehicles (HOV), Bus Rapid Transit and tolled Single Occupancy Vehicles. In addition, the project will replace several bridges, build a commuter bikeway, add Bus Rapid Transit improvements, and install Intelligent Transportation Systems (ITS) for tolling, transit and traveler information, and incident management. Phase 1 is currently under construction from Federal Boulevard to 88th Street in Louisville/Superior and will open to the public in 2015. Phase 2 from 88th Street to Table Mesa Drive in Broomfield recently began construction and will open in 2016.
