Using the Lanes

Anyone can use Express Lanes; there are simply different ways to travel them. A traveler can choose to travel:

Tolled Motorcycle


Travelers are never forced to pay a toll and can always choose to travel in the adjacent free general-purpose lanes.


The Express Lanes are easy to use.

For carpooling, go online to order your Switchable HOV Transponder and find two friends, family members or coworkers to join you on your trip. Once you have three or more people in your car, slide the tab on your transponder to the red "HOV" mode, and you can use the Express Lanes for free.

If you plan to travel with fewer than three people, paying a toll won't slow you down. You can use either a Switchable HOV Transponder or your current ExpressToll Transponder or sticker pass. Simply switch your transponder to the green "TOLL" mode, enter the lane in the designated area, and you are on your way.

If you choose not to use the transponder, you will be billed through a License Plate Toll. A bill will be sent to the registered owner of the vehicle and you will pay a higher toll rate based on how far you travel in the Express Lane.


* The I-70 Mountain Express Lane and C-470 Express Lanes do not include a "free" policy.


Pricing

  • Express Lanes use tolls to manage congestion and keep travel times reliable for all motorists.

  • Express Lanes will use a dynamic-pricing system in which tolls can change in price depending on the level of congestion—say, during peak morning or evening traffic. As traffic increases, the toll price goes up, helping to keep you moving in the Express Lanes.

  • Toll prices will vary based on each corridor. Visit the toll rates page to view the latest toll prices for your corridor.

  • Overhead signs will tell you exactly how much your trip will cost if you choose to use the lanes and pay a toll.

HOV-only users

Switchable HOV Transponders are now available for free to drivers who travel in the I-25 and US 36 Express Lanes, and plan to only use those passes for carpooling!

Previously, the transponders cost $15 for all drivers, but CDOT and its High-Performance Transportation Enterprise made the change to make carpooling easier for those who are dedicated to that mode of travel.

  • Drivers who use any other Colorado tolled facilities—like the I-70 Mountain Express Lane, E-470 or Northwest Parkway, and C-470 in the future
  • Drivers who use their pass in toll mode on the US 36 and I-25 Express Lanes
  • Drivers who receive the free pass must drive in HOV mode at least once in the first six months after receiving it to maintain an HOV-Only account.
  • Drivers who do not use the free pass within six months, or who use the pass in toll mode or on a tolled Express Lane, such as the I-70 Mountain Express Lane, will be charged the cost of the Switchable HOV Transponder.
  • HOV-Only drivers must have a driver and at least two passengers to use the Express Lanes for free.

Safety tips

Enforcement
While it might be tempting to use the Switchable HOV Transponder to avoid paying tolls, it is important to remember there is enforcement on the roadway. Our local law enforcement officers are out on the corridors; violations could cost up to $250.

Weaving in and out of the Express Lanes and crossing the double white line could result in a violation and up to $1,000 fine.
