The southbound span of the Interstate Bridge will see night lane closures starting Saturday, March 25 and continuing for eight nights.
The closures will begin at 10 p.m. each night with all lanes open by 5 a.m. All work is scheduled for completion the night of Saturday April 1.
At all times, one southbound lane will remain open. At times, the right two lanes will be closed, at times the left two lanes, the closures depending on the work under way.
During the project, crews will make deck joint repairs at the draw span and carry out additional maintenance work under the deck itself.
The Interstate Bridge is jointly owned by Oregon and Washington and maintained and operated by the Oregon Department of Transportation. The northbound span opened in 1917, the southbound span in 1958.
