The southbound span of the Interstate Bridge will be closed Saturday night, Oct. 14, for maintenance.

All southbound lanes will close at 10:30 p.m. Saturday, Oct. 14, and re-open by 6 a.m. Sunday, Oct. 15. The southbound sidewalk will be closed but the sidewalk on the northbound span will remain open.

During the closure, crews will raise the southbound drawbridge for maintenance to help ensure the lift span is in good working order for winter. Crews will take advantage of the closure to check the barrier gates, patch potholes and maintain light fixtures.

During the closure, southbound traffic headed to Oregon should take State Route 14 east to Interstate 205 and the Glenn Jackson Bridge south.  

The Interstate Bridge is jointly owned by Oregon and Washington and is operated and maintained by ODOT. The northbound span opened in 1917 and the southbound span in 1958.
