E-470 Public Highway Authority

The E-470 Public Highway Authority consists of eight member jurisdictions: Adams, Arapahoe, and Douglas counties and the cities of Aurora, Brighton, Commerce City, Thornton, and the town of Parker. Affiliate, non-voting members are the cities of Arvada, Broomfield and Greeley, and Weld County. Ex-officio members are the Colorado Department of Transportation (CDOT), Denver Regional Council of Governments (DRCOG) and the Regional Transportation District (RTD).

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 EXpresToll 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.
