DOUGLAS COUNTY –– The Colorado Department of Transportation will close westbound C-470 from University Blvd. to Broadway on Friday, January 18 from 9:30 p.m. to 7:30 a.m. This closure is necessary to perform a traffic switch onto permanent concrete pavement that will open the median work area for crews to continue permanent paving as part of the C-470 Express Lanes Project.

Detour: Exit University Blvd. westbound off-ramp. Turn right onto northbound University Blvd., proceed north to County Line Rd. and turn left. Continue on County Line Rd. for one and a half miles to Broadway. Turn left onto southbound Broadway, then continue to the westbound C-470 on-ramp. (Detour is approx. 2 miles)

Ramp closures

Crews will close the southbound and northbound I-25 ramps to westbound C-470 on Saturday, Jan 19 from 10 p.m. to 8 a.m. These closures are necessary to install temporary structures that will support construction crews as work continues on the E-470 to westbound Express Lanes Bridge.

Detour: Take northbound and southbound I-25 to northbound E-470 to Peoria exit. Take Peoria to southbound E-470 and continue onto westbound C-470. No tolls will be charged during closure.

Follow detour signs accordingly and go slow for the cone zone.

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

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

More than 100,000 motorists currently use this segment of C-470 each day with volumes projected to increase 40 percent by 2035.


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.
