The US 36 Express Lanes Project is a multi-modal project led by the Colorado Department of Transportation (CDOT) and the Regional Transportation District (RTD) to reconstruct US 36 from Federal Boulevard to Table Mesa Drive in Boulder.

CDOT selected the Ames Granite Joint Venture team as the design-build contractor for the $497 million project, and they began construction in July 2012. The project opened to the public winter 2016.

Project Details:

  • The US 36 Express Lanes Project is a multi-modal project that built an express lane in each direction on US 36, in addition to the two free general-purpose lanes.
  • The Express Lanes accommodate High Occupancy Vehicles (HOV), Bus Rapid Transit (BRT), which started running in January 2016, and tolled vehicles.
  • In addition, the project replaced several bridges, built a commuter bikeway, added BRT improvements, and installed Intelligent Transportation Systems (ITS) for tolling, transit and traveler information, and incident management.
