US 36 Express Lanes Project


US 36 Express Lanes Project

In partnership with CDOT, RTD and the Colorado HPTE, 36 Commuting Solutions and the US 36 Mayors & Commissioners Coalition have successfully assembled funding from a variety of partners to start the re-invention of US 36 into a multi-modal corridor.

As the largest CDOT project in the state, the $497 million undertaking will develop the US 36 Bikeway, Bus Rapid Transit (BRT) service, and a new Express Lane in each direction from Federal Boulevard to Table Mesa Drive in Boulder. The project began in 2012 and will be complete in early 2016. Visit the Construction Updates page to learn about progress on the US 36 Express Lanes Project.

These Express Lanes will be used for High Occupancy Vehicle (HOV), High Occupancy Toll (HOT) and Bus Rapid Transit (BRT), greatly alleviating congestion and providing US 36 commuters with more commuting options. CDOT has chosen the Ames/Granite Joint Venture as the design-build contractor and Plenary Roads Denver as the corridor’s concessionaire.

Project Elements

  • Active Traffic Management means that commuters will see digital signs displayed by the roadside on current traffic conditions. The information is collected in real time from cameras and vehicle detectors along the road. The ATM digital signs will be available by 2016 on US 36 between I-25 and Boulder, and southbound I-25 between US 36 and 120th Avenue.
  • Constructing an Express Lane in each direction of US 36 between Pecos Street and Table Mesa Drive for Bus Rapid Transit (BRT), High Occupancy Vehicles (HOV) and tolled Single Occupancy Vehicles (SOV).
  • Reconstructing two general purpose lanes in each direction between 88th Street in Louisville and Table Mesa in Boulder.
  • Widening the highway to accommodate 12-foot-wide inside and outside shoulders.
  • Replacing the Coal Creek bridge, rehabilitating and widening the South Boulder Creek bridge, and widening the McCaslin Boulevard bridge to accommodate a diverging diamond interchange
  • Adding BRT improvements including new electronic display signage at stations and bus priority improvements at ramps.
  • Building lanes for buses on the shoulders of US 36 between interchanges to decrease bus travel time.
  • Installing Intelligent Transportation Systems (ITS) for tolling, transit and traveler information and incident management.
  • Installing a separate commuter bikeway along the rest of the corridor.
  • Improving the RTD station at McCaslin Boulevard.
