December 10, 2021 - Southeastern Colorado - CDOT continues construction with installation of advance warning signage, emergency pullouts, pothole and rumble strip patching on Interstate-25 Resulting in daytime and nighttime lane closures

COLORADO SPRINGS — For the week of December 12 Colorado Department of Transportation and Contractor SEMA Construction, Inc. will work on Interstate-25 along a 7.5-mile segment between South Academy Boulevard and extending to the Santa Fe Avenue exit (CO 85/75). Work will take place during evening and early morning hours, with alternating right- and left-lane closures on I-25 to continue installation of permanent advance warning sign and construction of northbound emergency pullouts. Additional daytime work will require southbound I-25 single lane closures for pothole and rumble strip patching. Work will require a speed limit reduction to 55 MPH during construction hours.
