Toll Highway


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, terminating at I-25 on the north end of the metropolitan area just south of 160th Avenue.

The project was built in four separate phases, with construction on Phase 1 beginning in 1989 and ending with Phase 4 in 2003.

  • Phase 1 - Opened June 1991 - 5.1 miles
  • Phase 2/3 - Opened July 1998 - May 1999 - 29.3 miles
  • Phase 4 - Opened January 2003 - 12.2 miles

Toll collection is fully cashless effective July 4, 2009 either by EXpressToll transponders or through License Plate Toll camera photography.

The E-470 Authority's underlying $1.2 billion in bond debt is scheduled to be paid off in approximately 2039. CDOT has an option to take over E-470 in 2076 after the establishment of a perpetual maintenance fund and all debt is defeased.


Total - $1.23 billion

  • Phase 2/3 - $663 million
  • Phase 4 - $453 million
