As work accelerates on portions of the I-25 Expansion Project, the speed limit is dropping.

The speed limit on a four-mile piece of Interstate 25 Friday will drop from 65 mph to 55 mph  as work ramps up on  northbound and southbound I-25 between Woodmen Road and Black Squirrel Creek, which is located just south of  North Gate Boulevard.

Work in that stretch will include installation of guardrails, lights, signs and landscaping,  removal of a concrete barrier and grading and paving.

“As work increases and the protective concrete barrier is repositioned from the southbound lanes, driver and worker safety is requiring the speed reduction,” the Colorado Department of Transportation said Wednesday in a news release.

Nighttime speed limits remain at 45 mph in areas where traffic is restricted to one lane.
