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 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.
