Toll Rate Information
Plenary Roads Denver Assumes Operations and Maintenance Role for Toll Lanes
Plenary Roads Denver recently assumed operations and maintenance responsibilities for the I-25 Express Lanes. While that responsibility now falls on Plenary Roads Denver, ownership of the highway is always maintained by the public, through CDOT. The existing general lanes will also remain free for all commuters.
As part of the tolling agreement, tolling services will continue to be managed by ExpressToll, including billing and customer service. Express Lanes users are reminded that they will receive the lowest toll rates on all Colorado tolling facilities with an ExpressToll account. You can sign up for an ExpressToll account at expresstoll.com.
Express Lanes and transponders on I-25 will continue to function as usual through the transition period.
Express Lanes Overview
Express Lanes maximize the efficiency of High Occupancy Vehicle (HOV) lanes and help manage congestion on the highway. Rather than continuing to build lanes on congested highways, Express Lanes facilitate choice by allowing drivers to ride the bus, carpool or pay a toll. Buses, HOV vehicles and motorcycles are allowed in the lanes with an ExpressToll pass for free, while Single Occupancy Vehicles can choose to pay a toll.
Currently, those with two people in their vehicle can use the toll lane for free with a switchable transponder. However, starting Jan. 1 2017, all Express Lanes will require at least two passengers, for a total of three people, in a vehicle to use the lanes for free. Anyone with two or fewer people in their vehicle can either use the express lane and pay a toll, or use the general purpose lanes for free.
The I-25 Express Lanes includes seven miles on I-25, between downtown Denver and US 36.
CDOT opened Express Lanes on US 36, on I-70 east from Empire to Idaho Springs, and on I-25 from US 36 to 120th Avenue.
The I-25 Express Lanes opened on June 2, 2006.
Currently, CDOT is building Express Lanes on C-470, on North I-25 from 120th to Northwest Parkway/E-470 and from Johnstown to Fort Collins.
In addition, CDOT is including Express Lanes in the planning stages of other highway projects across Colorado—including I-70 East—as a way to effectively manage traffic congestion.
