BACKGROUND

The $276 million C-470 Express Lanes project will increase mobility and user choice along 12.5 miles between I-25 and Wadsworth Boulevard. In the westbound direction, two additional Express Lanes will be built from I-25 to Colorado Boulevard and one additional Express Lane from Colorado Boulevard to Wadsworth. In the eastbound direction, one additional Express Lane will be constructed along the length of the project between I-25 and Wadsworth Boulevard. The project also includes full reconstruction of existing pavement, the addition of auxiliary lanes at selected locations, on- and off-ramp improvements, realignment of substandard curves, widening of existing bridges, replacing the bridges over the South Platte River, the installation of tolling equipment and new C-470 trail underpasses at Colorado and Quebec. When complete, motorists will have the option to use the Express Lanes on C-470 for a faster, more reliable commute in exchange for paying a toll, or drive the general purpose lanes for free. Completion is scheduled for 2019.
