ODOT Begins Isthmus Slough Bridge Project March 14, 2018

A 20-month long Oregon Department of Transportation (ODOT) rehabilitation project on Isthmus Slough Bridge begins this week in Coos Bay, but there will be little impact to traffic the first few weeks. For most of March, work will take place under the west approach of the bridge and will not affect traffic. Later this month, motorists may begin to see intermittent nighttime (8 p.m. to 6 a.m.) lane closures on the bridge, which may result in delays up to 20 minutes. Flaggers will provide traffic control as needed. The contractor can close the bridge at night on 10 occasions, but no nighttime closures are planned this month. ODOT will notify the Coos Bay community as soon as we have a schedule for any bridge closures.

The City of Coos Bay will have emergency personnel stationed in Eastside when there are scheduled bridge closures. ODOT is the primary contact for this project.
