US 36 closed for four nights for girder installation on Sheridan Boulevard bridge and bikeway bridge installation

April 14, 2014 - Metro Denver Colorado/CDOT Region 1 - WESTMINSTER – The girders on the remaining portion of the new Sheridan Boulevard bridge will be installed over the course of three nights as part of the US 36 Express Lanes Project.

The Colorado Department of Transportation (CDOT) will close eastbound and westbound US 36 nightly, April 15-17, 11 p.m. to 5 a.m., for approximately a quarter of a mile on each side of the Sheridan Boulevard bridge. In addition, the installation of the bikeway and utility bridge, which was originally schedule for last Friday, will take place tonight, April 14, 9:30 p.m. to 5:30 a.m. The highway will also be closed for that work between McCaslin Boulevard and Interlocken Loop.

“We are installing 16 girders across the highway, each weighing approximately 88,000 pounds, so the closure is necessary to keep the traveling public safe,” said CDOT Project Director Mark Gosselin. “The girder installation marks construction of the final phase of the new bridge.”

Traffic will be detoured at the US 36 off-ramps to Sheridan and routed immediately back onto eastbound and westbound US 36 via the on-ramps.

The Sheridan Boulevard bridge is being built in two phases. The first phase opened in early 2014 at the same time that the old bridge was demolished. Following this girder installation, crews will pour the concrete deck of the bridge and build the US 36 ramps to and from the bridge. The final phase will be completed later this year.

The US 36 Express Lanes Project is a multi-modal project that will build an express lane in each direction on US 36 from Federal Boulevard to Table Mesa Drive in Boulder. The lanes will accommodate High Occupancy Vehicles (HOV), Bus Rapid Transit and tolled 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 (Federal Boulevard to 88th Street) will open to the public in 2015, and Phase 2 (88th Street to Table Mesa Drive) will open in 2016.
