I-25 North Express Lanes Between 120th and E-470/Northwest Parkway Open

News Release

January 31, 2020 - New lanes are free during toll testing phase

DENVER - The I-25 North Express Lanes between 120th Avenue and E-470/Northwest Parkway are fully open!  Motorists will be able to use the new lanes for free during a testing period of the toll system through late spring 2020. 


Cars drive on the new I-25 North Express Lanes between 120th Avenue and E-470/Northwest Parkway

Construction recently completed, adding one Express Lane in each direction on I-25 from 120th Avenue to just south of E-470/Northwest Parkway. Drivers now have the option of a continuous trip in the I-25 North Express Lanes from US 36 to E-470. 

In addition to the new Express Lanes, the project made the following improvements:

  • installed an auxiliary lane along northbound I-25 to connect the 136th Avenue on-ramp to the 144th Avenue off-ramp, which will help drivers merge more comfortably between the two interchanges;
  • resurfaced the roadway, which improves driving conditions;
  • made drainage and utility improvements along the corridor; and, 
  • enhanced technology and operations at ramps through traffic metering devices. 

Once toll testing is complete in late spring, motorists will have the choice of taking the Express Lanes for a faster, more reliable travel time in exchange for a toll.  Express Lanes will be free to vehicles with three or more people and motorcycles. All travelers will have the choice of taking the general purpose lanes for free. Express Lanes on other roadways in Colorado have improved travel times across all lanes. 

ExpressToll Pass 

To use any Colorado Express Lanes, you will need an ExpressToll account and pass to save money and not pay the License Plate Toll. The Switchable HOV Transponder is the only pass that allows you to choose the carpool option and use the lanes for free. For more information, go to www.expresstoll.com.
