Tolling Countdown Begins for US 36 Express Lanes from Louisville to Boulder

March 3, 2016 - Denver Metro/CDOT Region 1 - Toll commencement for the final phase of the US 36 Express Lanes project begins March 30, 2016.

BOULDER, CO – The Colorado Department of Transportation (CDOT), the High Performance Transportation Enterprise (HPTE) and private project partner Plenary Roads Denver today announced that toll collection, on the final US 36 Express Lanes segment in both directions from Superior/Louisville to Boulder, will begin Wednesday, March 30.

With this final stretch open, the US 36 Express Lanes project will be open from Federal Boulevard to Table Mesa in Boulder. For those who have not already done so, drivers are encouraged to get an ExpressToll account and pass. For carpoolers, the switchable pass is the only device that will allow them to travel in the lanes for free, and for single drivers, the pass saves them money by not having to pay a license plate surcharge. Both passes work on all Colorado Express Lanes, E-470 and the Northwest Parkway.

“We are nearing completion of this multi-modal project that offers biking, carpooling, transit, and toll travel options that provide users with reliable travel times,” said David Spector, HPTE director. “Travelers are already enjoying the operational benefits of US 36 as we are putting the finishing touches on this project.”

The US 36 Express Lanes Project is a multi-modal project with 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) and tolled vehicles. Sample toll rates were approved last year by the HPTE board, and can found here.
