ORIGINAL REPORT: Yes, that’s I-5 closures, plural, next weekend (Friday night, June 1st, through Monday morning, June 4th). Besides the northbound I-5 closure at the West Seattle Bridge that you’ve probably heard about, I-5 is also closing multiple NB lanes starting near Southcenter, and some SB lanes north of downtown. This afternoon, WSDOT provided this explanation of how it’s all going to unfold:
… Northbound I-5 lane closures will begin at the I-405 interchange near Southcenter before tapering down to a single lane that will exit at the West Seattle Bridge/Columbian Street/Spokane Street.
*All on-ramps to northbound I-5 between southbound I-405 and South Michigan Street except from eastbound SR 518 will close at 8 p.m. Friday.
*The SR 518 on-ramp to northbound I-5 will remain open all weekend.
*The northbound I-5 off-ramps all will remain open between southbound 405 and the closure at the West Seattle Bridge/Spokane Street/Columbian Way exit.
*The northbound express lanes will open afternoons with access only from the downtown on-ramps.
*A single lane of traffic will be able to enter northbound I-5 from the West Seattle Bridge/Columbian Street/Spokane Street on-ramp before heading into downtown.
*At the Duwamish River Bridge, three right lanes will be closed.
*At the southbound I-5 Lake Washington Ship Canal Bridge, the two left lanes will be closed from 3 a.m. to noon Saturday. The two right lanes and the 45th Avenue Northeast on-ramp will be closed from 3 to 11 a.m. Sunday.
A second weekend of major I-5 closures is tentatively planned for July 13-16. (We regularly include road-work reminders in our weekday-morning traffic coverage, but break out big things like this as merited.)
SATURDAY UPDATE: Two notes resulting from discussion in comments and elsewhere:
-You can check area traffic cameras any time on this WSB page
-You CAN get to eastbound I-90 via the exit to NB I-5 from the West Seattle Bridge – that’s been confirmed via a Twitter discussion with drivers who’ve done it as well as WSDOT.
