The lower deck of the Marquam Bridge, southbound Interstate 5, will be closed for inspections from 10 p.m.-6 a.m. Friday and Saturday nights, July 7-8.
During the closure, all southbound I-5 traffic must exit at the ramp to eastbound Interstate 84. Those wishing to continue south on I-5 should take Interstate 405 over the Fremont Bridge to rejoin I-5 south of the Marquam.
The westbound I-84 ramp to southbound I-5 will also be closed. Traffic will detour to northbound I-5.
During the closure, crews will use lifts and cameras to do a safety inspection of the bridge, according to a recent release from the Oregon Department of Transportation.
The Marquam Bridge opened in 1966 and has inspections every two years.
