Drivers in Western Washington should prepare for heavy traffic in the Seattle area this weekend. Several critical highway improvement projects will affect traffic flow on southbound 1-5 from the University District, across Lake Washington on I-90 and coming onto I-5 from the West Seattle Bridge.
West Seattle Bridge to I-5
• Ramps from the West Seattle Bridge to northbound I-5 and Columbian Way will be closed this weekend from 10 p.m. Friday until 5 a.m. Monday. The ramp from Sixth Avenue South to northbound I-5 and South Columbian Way also will be closed for expansion joint replacement and bridge support repair.
• Up to three lanes of southbound I-5 from Northeast Ravenna Boulevard to Boylston Avenue North will be closed Friday and Saturday nights from 10 p.m. until 10 a.m. for pavement grinding. The Ravenna on-ramp to southbound I-5 will also be closed during those hours. The I-5 express lanes will be open to southbound traffic from 9:45 p.m. until 1:30 p.m. the following day.
I-90 express lanes
• The I-90 express lanes will be closed from 11 p.m. Friday until 11 a.m. Sunday. During the closure, Sound Transit will survey and drill for soil samples as part of the East Link Extension light rail project. The Seattle portion of the I-90 express lanes will reopen by 6 a.m. Sunday, eastbound to Mercer Island only, for the Mercer Island Half Marathon.
