US 36 Express Lanes Phase 2
What you need to know about the Colorado Express Lanes
15 Days until US 36 Express Lanes to Boulder go live!

The second and final phase of the US 36 Express Lanes Project is currently open for testing. Drivers can use this phase of the Express Lanes between 88th Street in Louisville and Table Mesa in Boulder free of charge until tolling commences on March 30, 2016. Toll rates for Phase 2 were approved by the HPTE Board in October 2015. View the toll rates on the Tolling Fact Sheet.

If you already have an ExpressToll account and transponder that you’ve been using on Phase 1 of the US Express Lanes Project, you can continue using it on Phase 2. There are still two freegeneral purpose lanes in each direction on US 36, so you will always have a choice.

Sign up for ExpressToll

If you want to use the US 36 Express Lanes as a driver (not bus transit), you should get an ExpressToll account. Otherwise, you will receive a License Plate Toll bill and pay the higher toll rate. ExpressToll customers always receive the lowest toll rate on all Colorado tolling facilities. ExpressToll works on the following roads: US 36, I-25, E-470, Northwest Parkway, and the I-70 Mountain Corridor. Click here to sign up for ExpressToll.

Which transponder do I need?

If you will be using the Express Lanes in HOV/Carpool mode, then you will need an ExpressToll account with the Switchable HOV Transponder to drive for free. This switchable transponder costs $15. Watch for more information on the Switchable HOV Transponder. If you do not intend to use the Express Lanes in HOV/Carpool mode, then a regular ExpressToll sticker tag works just fine. This sticker tag is free.

Motorcycles need an ExpressToll account and a motorcycle tag to drive for free on the Express Lanes. If the motorcyclist already has an ExpressToll account, they simply need to add their motorcycle to that account at no additional charge. If a motorcyclist does not have an ExpressToll account, they will need to create one with the $35 balance of pre-paid tolls.
