Expect Overnight Closure of Eastbound C-470 from Quebec to I-25/E-470

DOUGLAS COUNTY—From 10 p.m. Wednesday, July 25 to 5:30 a.m. Thursday, July 26, crews will close eastbound C-470 from Quebec Street to the I-25/E-470 interchange for emergency repair work.

Due to recent flooding, crews will put in place mitigation measures to eliminate storm water from running onto Yosemite Street. Drainage improvements will include the addition of a V-shaped ditch, placing rock to create a dam, adding an inlet and piping.

This work is necessary for the safety of the traveling public as more rain storms are predicted through the summer.

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.
