Closures Planned for US 36 and Ramps This Weekend

June 5, 2015 - Denver Metro/CDOT Region 1 - Sheridan on-ramp and a highway closure required.

WESTMINSTER/SUPERIOR – Phase 1 of the US 36 Express Lanes Project is nearly complete, but some of the finishing touches will require a closure of the Sheridan Boulevard on-ramp to eastbound US 36 over the weekend starting June 5 at 10 p.m.through June 8 at 5:30 a.m.

This closure is necessary to complete the pavement and barriers. RTD buses will be flagged through.

On Phase 2 of the project (88th Street in Superior/Louisville to Table Mesa in Boulder), eastbound and westbound US 36 will be closed underneath the McCaslin bridge for two nights, June 8 and 9, 10 p.m.-5:30 a.m. Additional nights may be needed. Traffic will be detoured off and on the highway via the McCaslin ramps.

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

The two Express Lanes on Phase 1, from Federal Boulevard to 88th Street in Louisville/Superior, are now both open for testing, enabling travelers to try the road as a commuting option while toll collections are waived. The testing period will last until mid-July, when tolling will begin. Tolls on the existing I-25 Express Lanes, from Pecos Street on US 36 to downtown Denver, are still in effect. Phase 2, from 88th Street to Table Mesa Drive in Boulder, will open in 2016.
