[edit] Route description

The tollway begins at the I-25 / SH 470 interchange in Lone Tree and runs east and north through Aurora, intersecting with I-70. The highway continues north, passing west of Denver International Airport to connect with I-76 in Brighton and Commerce City before curving west and ending at an interchange with I-25 and the Northwest Parkway in Thornton.

[edit] The 470 Beltway

E-470 is the eastern portion of what was originally conceived as I-470, an outer beltway for metropolitan Denver. Plans for this eastern extension of State Highway 470 gained momentum in the 1980s, as Denver moved forward with plans for a new international airport in its corridor. Recognizing the highway's development potential, a number of local governments joined together to create the E-470 Public Highway Authority, a quasi-governmental entity that would construct the highway. The highway would be financed through tolls, a relative rarity in the western U.S. The first section, between I-25 in the south and Parker Road in Douglas County, opened in 1991. The highway was opened segment by segment until the final stretch connecting to I-25 in the north in Adams County opened for traffic in 2003.

The toll rate on E-470, roughly 27 cents per mile^{[citation needed]}, is one of the highest rates of any toll road in the United States.^{[citation needed]} E-470 was the first highway in the United States to implement full highway-speed electronic tolling. In its early years, traffic was light as the completed portion was short and traversed a largely undeveloped area. With the opening of Denver International Airport in 1995, E-470 came in as a direct route to the airport from the rapidly growing southern tier of the metropolitan area. Upon its completion, the highway provided the same access for northern Colorado, itself a high-growth area. However, perhaps the most significant growth in the region will occur in the E-470 corridor itself, which spawned numerous annexations by member cities; Commerce City, Colorado has doubled in land area in anticipation of this new development. In the coming decades, 250,000 new residents are expected along the E-470 corridor in Aurora alone, which would nearly double that city's population.

[edit] Ownership and management

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. In addition to all of these jurisdictions, E-470 also passes through the City and County of Denver near Denver International Airport. Affiliate, non-voting members of the Authority, which the highway does not directly serve, are the cities of Arvada and Greeley, and Weld County and the City and County of Broomfield. Ex-officio members are the Colorado Department of Transportation, the Denver Regional Council of Governments and the Regional Transportation District. The authority is headquartered in Aurora.
