E-470 is a 47-mile-long (76 km) controlled-access toll road that traverses the eastern portion of the Denver metropolitan area in the US state of Colorado.

Construction and operation involves no state or federal funding or taxes, with the exception of a $10 fee[2] originally charged on vehicle registrations for residents of Arapahoe, Adams, and Douglas counties.

The tollway begins at the I-25/State Highway 470 (SH 470, C-470) interchange in Lone Tree and runs east through the unincorporated community of Meridian and south of the Centennial Airport.

[7] Rental car companies at Denver International Airport have been accused of overcharging unwitting visitors for unpaid tolls because of the road's cashless collection system.

EZ TAG from the Harris County Toll Road Authority (HCTRA) system in Houston will be a future addition for ExpressToll users.

[9] E-470 is the eastern portion of what was originally planned as Interstate 470 (I-470), a full outer beltway for the Denver metropolitan area proposed by CDOT in the 1960s.

[13] In its early years, traffic was light as the completed portion was short and traversed a largely undeveloped area.

In 2006, the E-470 mainline was relocated about one-quarter mile (0.40 km) to the west to bypass the traffic signals and provide free-flowing conditions for toll customers.

[16] According to the 2015 E-470 Annual Report (page 3), "The widening is being constructed now to get ahead of the curve on future traffic volume, which has had double-digit growth in each of the past three years."
