Project Info

The $276 million C-470 Express Lanes project will increase mobility and user choice along 12.5 miles of the highway, between I-25 and Wadsworth Boulevard. On westbound C-470, crews will build two additional Express Lanes from I-25 to Colorado Boulevard, and one additional Express Lane from Colorado Boulevard to Wadsworth. On eastbound C-470, they will build one additional Express Lane 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 may 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.
