U.S. 36 to close overnight for installation of 120,000 bridge at McCaslin Boulevard

LOUISVILLE, Colo. - Installation of a new 120,000 pound bridge will close part of Highway 36 overnight Friday into Saturday.

The Colorado Department of Transportation says both directions of the highway will close from 9:30 p.m. until 6 a.m. from InterLocken Loop to McCaslin Boulevard -- mile markers 43-46. The new bridge is expected to be lifted into place between 11:30 p.m. and 12:30 a.m.

Anyone interested in watching the work could see if from the area of Avista Adventist Hospital. Parking will be available near the Flatirons Surgery Center on Health Park Drive.

McCaslin Boulevard is being turned into a "diverging diamond interchange," an unusual traffic pattern that will have drivers cross the bridge on the left side of the roadway, similar to driving in the UK. For drivers using the McCaslin Boulevard off-ramp in either direction, instead of waiting at a red light to turn left, they will immediately merge onto the closest lane on the left side of the bridge. They won't hit a stop light until they have crossed the bridge, when the lanes start to go back to the appropriate side of the street.

The project will cost slightly over $12 million. The Town of Superior is paying more than $5 million, the City of Louisville is paying about $3.5 million, RTD is paying $3.5 million and CDOT is contributing $950,000.
