CO 145 Widening West of Society Turn

About the Project

Williams Construction will be performing road work on Colorado Highway 145 at Mile Point 71, just west of the Society Turn Roundabout. 

Construction will include:

• Shoulder work
• Pavement widening
• Fresh paint striping

 This access improvement project is for a private development being funded by Genesee Properties, Inc. The design and construction is permitted and overseen by CDOT traffic and safety staff. The work is expected to be completed by early September.

Project Benefits

To accommodate future traffic patterns, the road will be widened to allow for a new right-hand turn lane including acceleration and deceleration lanes.
