Project Info

The $276 million C-470 Express Lanes project will increase mobility and user choice along 12.5 miles between I-25 and Wadsworth Boulevard. Crews will add two Express Lanes on westbound C-470, from I-25 to Colorado Boulevard, and one Express Lane from Colorado Boulevard to Wadsworth. They also will add an Express Lane on eastbound C-470, between I-25 and Wadsworth Boulevard.

Crews will fully reconstruct existing pavement; add auxiliary lanes at selected locations; improve on- and off-ramps; realign substandard curves; widen existing bridges; replace the bridges over the South Platte River; install tolling equipment; and build new C-470 trail underpasses at Colorado and Quebec.

When complete, the improvements will give motorists the option of using the Express Lanes on C-470 for a faster, more reliable commute in exchange for paying a toll. Or, they may drive the general purpose lanes for free.
