US 36 Express Lanes (Phase 1)

Close

US 36 is a four-lane divided highway that connects Boulder, Coloradoto with I-25 and the City of Denver. The highway experienced significant congestion and had been targeted for improvements by the Colorado Department of Transportation (CDOT) since the late 1990s. The US 36 Express Lanes Phase 1 project is an initial 10-mile segment along the 16-mile corridor between the two cities. This $306 million project was delivered under a design-build contract and includes the following components: One express, high occupancy toll (HOT) lane in each direction from Federal Boulevard to 88th Street in Louisville/Superior (approximately 10 miles) and reconstruction of the general purpose lanes Replacement of the Wadsworth Parkway, Wadsworth Boulevard, Lowell Boulevard, and Sheridan Boulevard bridges and replacement of the US 36 bridge over the BNSF Railway Bus rapid transit (BRT) accommodations at stations located on ramps and adjacent park-n-rides, and bus bypass ramps at several interchanges (new and more frequent bus service will be provided) Bikeway along much of the corridor Intelligent transportation system (ITS) equipment, including for tolling, transit information, and incident management Improvement of Regional Transportation District (RTD) stations along the corridor A second phase, which opened in January 2016, extends the HOT lanes five miles to Table Mesa/Foothills Parkway in Boulder. Phase 2 is being delivered as a design, build, finance, operate, and maintain public-private partnership. The private partner operates and provides routine maintenance and lifecycle maintenance on the Phase 1, Phase 2 and the existing I-25 Express Lanes under a 50-year agreement.
