The Latest C-470 Lane Closure Updates

in Roadways& Traffic

Notice of Extended Closure:

To eliminate the need for more than 20 nights of full closures, CDOT will conduct an extended right lane closure on the Quebec St. on-ramp to westbound C-470. The left lane of the on-ramp will remain open.

This closure will begin on Friday, December 13 at 8am and will continue through Wednesday, December 18 at 5:30am.

The closure is necessary to tie in the new permanent concrete pavement on the ramp to the existing concrete on Quebec St. It will allow crews to safely complete paving operations while allowing the traveling public to maintain usage of the ramp.

For your own safety and for the safety of our crews, watch for construction vehicles entering and exiting mainline C-470, obey all posted signage in construction zones and avoid distracted driving, especially in the work zone. Your safety and the safety of our crews is our highest priority.
