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 https://www.expresstoll.com/.
Express Lanes and transponders on I-25 will continue to function as usual through the transition period.
Express Lanes Overview
What is the Express Lanes concept? 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.
How can HOVs use the lanes for free? Currently, those with two people in their vehicle can use the toll lane for free with a switchable transponder. However, starting in 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.
Where are the Express Lanes located? The I-25 Express Lanes includes seven miles on I-25, between downtown Denver and US 36.
CDOT is extending the Express Lanes on US 36 as part of the US 36 Express Lanes Project. The new lanes will be extended to 88th Street in Louisville (opening in 2015) and then to Table Mesa Drive in Boulder (opening in 2016).
When did the Express Lanes open on I-25? The I-25 Express Lanes opened on June 2, 2006.
Are Express Lanes being built elsewhere in Colorado? Currently CDOT is building Express Lanes on two highways – US 36 and I-25 (north of US 36).
The US 36 Express Lanes Project will build an express lane in each direction on US 36 from Federal Boulevard to Table Mesa in Boulder. The project is being built in two phases with Phase 1 (Federal Boulevard to 88th Street in Louisville) opening in July 22, 2015, and Phase 2 (88th Street to Table Mesa in Boulder) opening in early 2016. These lanes will connect with the current Express Lanes on I-25. Click here for more information.
The I-25 North Express Lanes Project will add one express lane in each direction of I-25 between US 36 and 120th Avenue. This new lane will connect to the existing I-25 Express Lanes to and from downtown Denver.
In addition, CDOT is including Express Lanes in the planning stages of other highway projects across Colorado – including I-70 East and West and C-470 – as a way to effectively manage traffic congestion.
