E-470 is a 47-mile-long (76 km) controlled-access toll road traversing the eastern portion of the Denver-Aurora Metropolitan Area in the US state of Colorado. The toll road is not a state highway, but is instead owned and maintained by the E-470 Public Highway Authority, which is controlled by a governing board of eight elected officials of local governments. Construction and operation involves no state or federal funding or taxes. As of 2013, 85% of its revenues were derived from tolls. The road, which is one of the main highways providing access to Denver International Airport, has frequently come under fire for charging excess fees against visiting rental car users who unwittingly used the road.
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.
The 470 beltway
E-470 is the eastern portion of what was originally conceived as I-470, an outer beltway for metropolitan Denver. The quasi-government entity that manages the highway, 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.
The toll rate on E-470, roughly 36 cents per mile (22 ¢/km), is one of the highest rates of any toll road in the United States. There are five toll stations along the 47-mile (76 km) route and the average toll to pass each is $3.33. Traveling the entire length of the road from I-25 in the north to I-25 in the south (or vice versa) costs $13.25 for ExpressToll customers, and $16.65 for those without a transponder. The toll stations no longer accept cash; E-470 was one of the first highways in the United States to implement full highway-speed electronic tolling. Cameras at each station photograph the front and rear license plate of each vehicle. A bill is mailed after approximately 30 days to the registered owner of the vehicle in accordance with C.R.S 43-4-506.5 (6)(a). Failure to pay the bill on time results in a $5 late fee after 30 days, followed by a $15 collection fee after 60 days, and a $25 penalty after a total of five months, and then an additional $20 court charge after six months totaling a maximum penalty of $65 for each unpaid set of tolls.
Drivers with EXpressToll accounts, E-470's automated toll collection service, and transponders mounted on their vehicle save 20% on posted toll rates along E-470.
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. In 1987, the Public Highway Authority Law was passed by the Colorado State Legislature, giving the E-470 Public Highway Authority the power to do everything needed to plan, design, finance, construct, and operate the toll 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 to traffic June 1, 1991. Tolling began on July 15, making E-470 the first highway in the United States to implement open road electronic tolling. The highway was opened segment by segment until the final stretch connecting to I-25 in the north in Adams County opened on January 3, 2003.
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.
Up until 2006, E-470 had four signalized intersections with I-70 and its outer roads, which often got congested at peak hours. By 2004 this interchange proved too inadequate for the traffic it was receiving. The Fly-By was completed in 2006 and allows customers to bypass the signals if continuing on E-470. Traffic going to or from I-70 still uses the old road and intersections, although E-470 is currently in the process of designing a direct connection with I-70. In 2007, Ramp H was completed, providing a direct connection from northbound E-470 to westbound I-70. The I-70/E-470 Fly-By Interchange Complex in Aurora was recognized by the Design Build Institute of America (DBIA) with a National Design Build Award in 2008.
In November 2014, an additional interchange opened at Quebec Street in Thornton.
