The Oregon Department of Transportation (ODOT) reports that all northbound lanes of the I-5 Interstate Bridge will be closed from 11:00 p.m. Saturday, April 20 to 7:00 a.m. Sunday, April 21 for the bridge’s biennial inspection.
As a detour, Washington-bound traffic should take Interstate 84 east to Interstate 205 north across the Glenn Jackson Bridge over the Columbia River.
During the closure, a team will inspect the bridge’s most critical steel members as part of the analysis to make sure the structure remains sound. This is the inspection most bridges undergo every two years. During the closure, crews will also build a sign bracket and replace traffic control lights over all three northbound lanes.
The sidewalk on the northbound span will also be closed but the sidewalk on the southbound span will remain open.
The Jantzen Beach on-ramp to northbound I-5 will be closed during the same hours.
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.
