E-470

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 maintained by the E-470 Public Highway Authority, which is controlled by a governing board of ten elected officials, three from each county and one from Aurora. Construction and operation involves no state or federal funding or taxes.
