Coos and Curry County motorists can expect traffic delays at these road construction projects this week, according to the Oregon Department of Transportation and the Coos County Road Department:

Coos County

n U.S. Highway 101 (Oregon Coast Highway), milepost 233.4-234.5, McCullough Bridge rehabilitation (north section): This five-year project will help prevent corrosion on the McCullough Bridge by applying a cathodic protection treatment to the northern concrete arches of the structure. Watch for nighttime (9 p.m.-5 a.m.) lane closures across the bridge. Flaggers and pilot cars will provide traffic control as needed. The sidewalk on both sides of the bridge has been reduced to three feet in width during construction. Due to construction activity and safety concerns, the access road at the northeast corner of the bridge is restricted. Only ODOT employees and contractors are permitted in this area. Please do not drive or park on the access road.

n U.S. Highway 101 (Oregon Coast Highway), milepost 234-238, North Bend to Coos Bay paving, sidewalks and traffic signals: Construction is mostly complete. Watch for intermittent lane, shoulder and sidewalk closures throughout the project area.

Curry County

n U.S. Highway 101 (Oregon Coast Highway), milepost 330-331, Hunter Creek Bridge cathodic protection: Watch for workers and equipment in the roadway. A temporary traffic signal is in operation. Flaggers will provide additional traffic control as needed.

Westbound traffic will follow the same route in the opposite direction. During the nighttime closures, workers will only open the tunnel for emergency service vehicles. All other traffic must use alternate routes. During daytime hours, motorists should watch for intermittent single-lane closures and brief delays. Flaggers will provide traffic control as needed.
