Express Lanes

 What are Express Lanes?

Express Lanes provide travelers with more reliable, predictable travel times. Anyone can use Express Lanes. A solo driver in a passenger vehicle can use an Express Lane by paying a toll. A traveler can choose to travel for free on a motorcycle or as a carpooler with two passengers plus the driver.

The addition of an Express Lane on the I-25 corridor does not mean that existing general-purpose lanes will be tolled. The existing general-purpose lanes are currently free to use and will continue to be free to use.


  • Reduce delay on Colorado's most seriously congested corridors
  • Use toll pricing to manage congestion.
  • Maintain reliable travel times now and in the future.
  • Promote transit and carpooling.

 Toll Pricing

Express Lanes help manage traffic congestion, and toll rates will vary by time of day to provide reliable travel times.

Toll rates have not yet been set. The toll rates and any rate changes will be approved by CDOT's High Performance Transportation Enterprise.
