The Washington Department of Transportation (WSDOT) has scheduled several construction projects this week that will result in various lane and ramp closures across the region. Key highlights include:
-
Bellevue: Full closure of all northbound lanes on Interstate 405 (I-405) between Southeast 8th Avenue and Northeast 4th Avenue from March 10-13, with nightly closures from 11 PM to 4:30 AM for ongoing expansion work.
-
Seattle: Lane closures on I-5 southbound from Northeast 45th Avenue to Mercer Street on March 10-11, followed by closures on I-5 northbound from Harbor Avenue to Mercer Street on March 12-13. Major renovations to the ship canal bridge have been delayed until 2026.
-
Snoqualmie: The I-90/SR 18 interchange will see various lane and ramp closures throughout the week due to the I-90/SR 18 Interchange Improvement Project.
- Seatac: The southbound I-5 off-ramp to South 188th Avenue will be closed nightly from March 10-14. Additionally, Seattle Port crews will be conducting lane closures for sign replacements at Seatac Airport.
These closures are mainly scheduled during overnight hours to minimize impacts on drivers.
