Driver & Pedestrian Notice:

Drivers and pedestrians may notice intermittent construction activities as crews coordinate work around weather conditions and specialized operations. Traffic control devices, including barrels, will remain staged throughout the project area to maintain safe traffic patterns, protect work zones, and allow crews to mobilize quickly when conditions allow–even during periods when active construction is not taking place.

Construction activities will continue to shift throughout the project area as crews complete as much work as possible during winter conditions. Drivers and pedestrians are encouraged to use caution, plan for extra travel time, and follow posted signage and traffic control measures. 

Ongoing Activities

I-15 Lane Closures & Shifts

Crews will complete nighttime intermittent lane shifts and closures on I-15 in both northbound and southbound directions through the month of May for profile and concrete grinding activities. During this work, traffic will shift to the three middle lanes. Pavement grinding smooths the concrete surface to improve the ride quality for drivers. 

Plan ahead and expect delays during peak travel times.
