Tolling in Colorado

Information on the I-25 Express Lanes, public-private partnerships and other innovative and efficient means of completing surface transportation infrastructure projects.
I-25 HOV Express Lanes
Express Lanes maximize the efficiency of HOV lanes by moving more people not more cars. Express Lanes allow those who drive alone (also known as "single occupant vehicles") to use the Express Lanes if they pay a toll or to travel as a carpooler for free, using a switchable transponder.
High-Performance Transportation Enterprise (HPTE)
The business purpose of the Transportation Enterprise is to pursue public-private partnerships and other innovative and efficient means of completing surface transportation infrastructure projects.
