Proposed Lanes Image​I-25 North Express Lanes Project

In the fall of 2013, the Colorado Department of Transportation began a $60 million project on I-25 between US 36 and 120th Avenue. The I-25 North Express Lanes Project will utilize the existing infrastructure to expand the capacity of I-25 by adding an HOV/tolled Express Lane in each direction on the inside shoulder of the interstate.

The new HOV/tolled Express Lane will connect to the I-25 Express Lanes currently in place between downtown Denver and US 36. In addition, six miles of the existing lanes between US 36 and 120th Avenue -- which will remain general purpose lanes -- will be resurfaced. When the project is complete in late 2015, buses and carpools may use the new lanes free of charge while solo  drivers will be required to pay a toll. The toll rates have not yet been set, but the rates will vary depending on travel demand.
