All northbound lanes of Interstate 405 will close for pavement repairs this weekend in Bellevue, while the northbound interchange from Highway 167 to northbound I-405 will also close to replace a corroded drainpipe in Renton.
Closures begin at 10 p.m. Friday and last until 5 a.m. Monday. The dual projects are likely to cause delays. The state Department of Transportation asks drivers to spend a few minutes to plan an Eastside detour, switch to I-5 going north, carpool, or brace for a longer trip.
The Bellevue project will close northbound lanes between the Southeast Eighth Street/116th Street Southeast exit and Highway 520. Also, the I-90 ramps to northbound I-405 will close. Contractor crews will replace concrete freeway panels that are nearly 50 years old, next to downtown Bellevue.
Also, I-405 northbound from Highway 520 to Northeast 70th Street in Kirkland will be reduced to one lane from 2 a.m. to 7 a.m. Sunday and from 1 a.m. to 5 a.m. Monday, for overnight pavement grinding.
In Renton, the Highway 167 ramps to southbound I-405, and from Rainier Avenue South to northbound I-405, will remain open.
Spillover traffic this weekend could affect I-5 through downtown Seattle, as well as the Highway 520 toll bridge.
Traffic will be affected by a baseball game at 6:10 p.m Saturday, against the Milwaukee Brewers, when Ken Griffey Jr. will be inducted into the Seattle Mariners Hall of Fame; and another game against the Brewers at 1:10 p.m. Sunday.
The INRIX traffic-data firm, based next to Highway 520, suggests that drivers in Bellevue travel before 10 a.m., to avoid afternoon slowdowns. During a previous closure, Bellevue Way and 148th Avenue Northeast became congested mid-day, and didn’t return to normal until 6 p.m.
