US 36 Closed Nightly This Weekend for First Major Bridge Demolition

September 19, 2013 - Denver Metro Colorado/CDOT Region 1 - BROOMFIELD – The Colorado Department of Transportation (CDOT) will close US 36 nightly, Sept. 20-23, to demolish the 112th/Olde Wadsworth bridge in Broomfield, the first of the old major bridges on the US 36 Express Lanes Project to be demolished.

For safety, the work will require a full closure of east and westbound US 36, from Church Ranch to Wadsworth Parkway, at the following days and times:

  • Friday and Saturday, 9 p.m.-8 a.m.
  • Sunday, 8 p.m.-5:30 a.m.
  • Monday, 10 p.m.-5:30 a.m.

The detour uses Wadsworth Parkway and Church Ranch Boulevard. Delays should be expected, and drivers are encouraged to avoid the area if possible. CDOT would like to remind motorists to obey all construction signs and flaggers and to “Slow for the Cone Zone.” All affected RTD bus stops, including the Church Ranch Park-n-Ride and the US 36 & Broomfield Park-n-Ride, will be temporarily relocated, and signs will be posted to direct riders to the temporary bus stops.

Built in 1951, the 112th/Olde Wadsworth bridge is being replaced with the new Uptown Avenue bridge, which will open in early October. It is one of five bridges being completely rebuilt as part of the US 36 Express Lanes Project. Three more will be widened to accommodate additional lanes on the highway. The old Wadsworth Parkway bridge will be demolished in October, with the new bridge opening in phases that same month.

“Our first bridge demolition brings us one step closer to completing one of the biggest elements of this project – the construction of all of the new bridges,” said US 36 Project Director Mark Gosselin. “It is a very visible milestone, and one that we are excited to reach.”

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, currently under construction, will build the project from Federal Boulevard to 88th Street in Louisville/Superior. Phase 2, which is expected to begin construction this winter, will extend the project from 88th Street to Table Mesa in Boulder.

Ames/Granite Joint Venture team is the design-build contractor for the project, which began in summer 2012 and will open to the public in January 2015. Phase 2 will open to the public in January 2016.
