I-25 Express Lanes
Now all carpoolers that use the HOV-lane on I-25 must have three people in the vehicle.
What you need to know about the North I-25 Express Lanes:
The North I-25 Express Lanes are available 24 hours a day, however, they connect to the existing Central I-25 Express Lanes which are reversible lanes that are open in certain directions at different times of the day. As part of this project, there is a new connection to the existing Express Lane section that forces southbound traffic back on I-25 by 70th Street when the reversible lanes are northbound. Note: Vehicles should not cross the solid white line to access the Express Lane; enter and exit at the designated areas only, shown with a white dotted line.
Northbound travelers: There are three northbound entries to the new Express Lane. Similar to the I-70 Mountain Express Lane, one toll is charged for the entire section. (CDOT wants to encourage throughput and will charge one price for the whole section, no matter where the driver enters.) From northbound I-25, entrances are: before 84th Avenue, before Thornton Parkway, and before 104th Avenue.
Southbound travelers: There are three entrances to the southbound I-25 Express Lanes: After 120th Avenue, before Thornton Parkway and before 84th Avenue. Entrances to the existing Express Lanes to Denver are at the I-270 exit ramp and another chance to enter right after the I-270 exit.
US-36 to I-25 travelers: If you are driving from the US 36 Express Lanes to the northbound North I-25 Express Lane, you must exit the US 36 Express Lanes and then re-enter the North I-25 Express Lanes at 84th Avenue.
Solo-Drivers: If you plan to use the Express Lane as a tolled vehicle, be sure to get a pass to receive the discounted toll rate. Go to www.expresstoll.com to get the pass that is right for you. The same ExpressToll passes (stickers or switchable transponders) that are used on CDOT’s Express Lanes on US 36, I-25 (existing), and I-70 Mountain, as well as E-470 and the Northwest Parkway will work on the North I-25 Express Lane. Travelers will be charged the toll price posted when they entered an Express Lane. If the price should increase or decrease while they are in the lane, drivers will pay the price posted upon entry.
Carpoolers/HOV travelers: If you plan to use the Express Lane for free as a three-person carpool, you need to have a Switchable HOV Transponder. If you do not have this transponder, you will be charged either a license plate toll or an AVITOLL (for cars registered at expresstoll.com) regardless of how many passengers you have in your vehicle.
About the North I-25 Express Lanes Project:
The North I-25 Express Lanes used existing infrastructure to expand the capacity of I-25 for six miles, from US 36 to 120th Avenue, by adding an Express Lane in each direction on the inside shoulders. In addition, the project resurfaced the existing lanes in this six-mile stretch, lowered the profile of I-25 under the 88th Avenue bridge to increase truck traffic safety, reconstructed the connection area of the existing Express Lanes and their ramps to I-25, constructed new concrete noise barriers, and installed new highway signage that includes CDOT’s Active Traffic Management system that alerts drivers of incidents. Construction began in 2013, and the lanes opened for tolling in July 2016.
About Express Lanes
Express Lanes increase roadway capacity and help to manage congestion on the highways. The use of toll pricing during peak travel times reduces delays, manages congestion and maintains reliable travel times. For more information, visit expresslanes.codot.gov.
