Roads

E-470 is a toll highway that runs along the eastern perimeter of the Denver metropolitan area. The 47-mile beltway extends from State Highway C-470 at I-25 in Douglas County south of Denver, runs east and then north through Aurora, passes along the western edge of the Denver International Airport, and turns back towards the west, ending at I-25 on the north end of the metropolitan area.

Express Lanes are located adjacent to free general purpose lanes, helping alleviate congestion on the road. There are Express Lanes located on I-25 from downtown Denver to US 36. Coming later this year, there will be additional Express Lanes located on US 36 between downtown Denver and Boulder, on I-70 West in the mountains and on north I-25.

The Northwest Parkway is a 75-mile per hour public toll road that seamlessly connects E-470 at I-25 in the north metro Denver area, with U.S. 36 in Broomfield. Click here to learn more about the Northwest Parkway and the Go-Pass toll collection system.
