SEATTLE – Work on several major roadways is expected to have a ripple effect for traffic on both sides of Lake Washington this weekend.
In Seattle, contractor crews working for the Washington State Department of Transportation will close all but a single lane on the northbound Interstate 5 collector-distributor to replace worn and aging expansion joints from Friday, March 21 until Monday morning, March 24. Also, the State Route 99 Alaskan Way Viaduct will be closed for additional inspection work, Saturday, March 22.
The Seattle Department of Transportation will have a nighttime closure on southbound SR 99 as well as daytime closures of the Mercer Street ramps to I-5 as part of the Mercer Corridor Project.
Eastside drivers will need to use alternate exits on I-405 to reach downtown Bellevue as the southbound off-ramp to Northeast Eighth Street will be closed all weekend for drainage and barrier work.
“We don’t usually see this much roadwork so early in the year, but this will help us preserve our aging highways and it just can’t wait,” said WSDOT Regional Administrator Lorena Eng. “Drivers play an important role in keeping traffic moving, and can help the freeway system out by carpooling, taking transit or delaying discretionary trips.”
Weekend closure details:
10 p.m. Friday, March 21 until 5 a.m. Monday, March 24
8 a.m. until 6 p.m. Saturday, March 22 and Sunday, March 23
SR 99 Closures
11 p.m. Friday, March 21 until 10 a.m. Saturday, March 22

11 p.m. Friday, March 21 to 4 a.m. Monday, March 24
Keeping traffic moving
WSDOT is doing everything possible to help keep traffic moving including:
WSDOT needs help from drivers to keep traffic moving
Drivers should plan ahead for construction and create a commuting strategy:
The work on I-5 is part of the $2.8 million Seattle Expansion Joint Replacement Project. Expansion joints help maintain a smooth driving surface by allowing a highway to expand and contract with changing weather. Not only does replacing old expansion joints help preserve I-5 well into the future, it also saves drivers hours of unexpected delays caused by emergency highway repairs.
The is the seventh of nine weekend closures to replace 26 bridge expansion joints on I-5 near the I-90 interchange.
The work on I-405 is part of the $334 million Bellevue to Lynnwood Widening and Express Toll Lanes project that will add a lane in each direction to help alleviate congestion. For more information, please visit the project website.
