Crews to Close Eastbound C-470 at Broadway Overnight Dec. 1

DOUGLAS COUNTY—From midnight on Friday, Dec. 1 through 5 a.m. Saturday, Dec. 2, CDOT will close eastbound C-470 at Broadway to complete work for the C-470 Express Lanes project. This closure allows crews to move a concrete paver across the highway.

Motorists will be detoured onto the Broadway on- and off-ramps to return to C-470. Detours are less than one mile.

Follow detour signs accordingly and travel slowly through the cone zone.

Construction activities are weather dependent and the schedule is subject to change.

For motorists on C-470, courtesy patrol is provided at no cost to drivers from 6 to 9 a.m. and from 3:30 to 6:30 p.m., Monday through Friday to assist disabled vehicles.

More than 100,000 motorists currently use this segment of C-470 each day with volumes projected to increase 40 percent by 2035. Construction is scheduled for completion in spring 2019.

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.
