Upcoming, motorists will encounter 24/7 lane reductions (one lane in each direction) in the area, with added stop signs. Motorists are required to slow to a stop and then travel slowly in the uneven pavement area. A 25 miles-per-hour speed reduction will be in place in the project area. Travelers should also plan for intermittent one-way traffic control with up to 15-minute delays, 24/7 when in place. Motorists are urged to slow down and drive carefully in and around construction areas, follow speed limit reductions in place and allot extra time for delays.
