E-470’s Road Widening Project, aimed at providing improved mobility by adding a new third lane in each direction along the toll facility between Quincy Avenue and Parker Road, is officially complete. The eight-mile project will allow E-470 to accommodate projected growth in the coming years and continue to maintain a free flow of traffic for customers.

A 2014 study of the E-470 Public Highway Authority indicated the section of roadway between Quincy Avenue and Parker Road would need to be widened by 2018 in order to continue operating at the same level of service desired by customers. The Authority, which is user-financed, began work on the approximately $90 million project in the spring of 2016. The new lanes opened to the public on October 16, two months ahead of the originally projected schedule. Final work on signage, landscaping and lighting is ongoing, but anticipated to wrap up in the coming weeks.

The project also included the construction of a new regional trail along the west side of E-470 between Quincy Avenue and Ireland Way, which opened to the public on December 1. The trail has been constructed past the designated end point at Ireland Way, along the E-470 right of way to the Arapahoe/Douglas County line, although this section is not yet open to the public. The Town of Parker is working with neighboring jurisdictions to determine the connectivity and final design for the trail reaching to the Cherry Creek trail west of Parker Road. E-470 sees the construction of the trail as laying the groundwork for future connections and travel options in the area through partnerships with the local jurisdictions.

“The Road Widening Project provided us with an opportunity to explore other steps, like the trail and added lanes, that we could take now to prepare for enhanced connectivity and options in the future,” said Tim Stewart, E-470 Executive Director. “The larger focus of the project—adding roadway capacity—will allow us to meet customer demand and continue to provide a safe and reliable journey for travelers. This, coupled with our freeze on toll rates for ExpressToll customers should reinforce E-470’s commitment to customers and as a mobility option for the region.”

Last month, the E-470 Board of Directors announced a toll adjustment that will freeze toll rates for ExpressToll drivers on the 47-mile user-financed roadway through 2020, pending annual board approval. In addition, the ExpressToll toll rate at Plaza C (on E-470 between I-70 and Peña Boulevard) will decrease by $.25. Meanwhile, License Plate Tolls (LPT) will be adjusted to cover the higher cost of collections, increasing the premium that LPT customers pay over ExpressToll customers. The ExpressToll and LPT toll adjustments for E-470 will go into effect January 1, 2018.

E-470 is the 75-mph toll road running along the eastern perimeter of the Denver metropolitan area. E-470 is a user-financed roadway, receiving no local, state or federal funds for financing, construction, operations or maintenance. E-470 is a political sub-division of the state governed by the E-470 Public Highway Authority Board composed of eight local governments including Adams, Arapahoe and Douglas counties, and the municipalities of Aurora, Brighton, Commerce City, Parker and Thornton. E-470 also operates ExpressToll, the all-electronic toll collection system available on E-470, Northwest Parkway, and Colorado’s Express Lanes.
