I-5 Lane Closures in SODO this Weekend — and Again July 4 Weekend
Construction crews will close most of southbound Interstate 5 in Sodo again this weekend, this time blocking all merges from Interstate 90 into southbound I-5.
The disruptions could make travel harder during Sunday’s Seattle Pride Parade downtown, where 200,000 to 500,000 people are expected. Sound Transit light rail will provide normal service downtown with trains every 10 minutes leaving Northgate and SeaTac.
And the Washington State Department of Transportation announced it will also do I-5 roadwork July 2-3 during Independence Day weekend, a departure from its previous strategy to give drivers a holiday break.
The extra closures are to compensate for two rained-out weekends in May, and for taking last weekend off, while parallel route Interstate 405 was closed for overpass demolition in Bellevue.
WSDOT says this is the third of 15 weekend shutdowns in 2022 to replace worn-out steel expansion joint edges and covers with stronger epoxy and silicone joints, to maintain road decks built in the 1960s. Expansion joints are small gaps that allow thermal movements in the concrete.
