Via the Washington State Dept. of Transportation:
SEATTLE – Weekend drivers need to plan for long travel delays and added congestion as two major construction projects are underway in Seattle and Bellevue this weekend, Aug. 25-28.
Lane reductions on northbound Interstate 5 between Tukwila and Seattle and a full closure of Washington State Route 520 between Seattle and Bellevue will also add congestion to Interstates 90 and 405 as drivers try to avoid the closures.
The major pavement preservation project on northbound I-5 shifts gears this weekend as contractor crews working for the Washington State Department of Transportation begin expansion joint replacement on the Interurban Bridge. Crews will also pave the Interurban and Duwamish River bridges.
Drivers should expect:
- Only two left lanes between I-405 and the Duwamish River Bridge will be open from 8 p.m. Friday, Aug. 25, to 5 a.m. Monday, Aug. 28
- Lengthy delays getting to and from Sea-Tac International Airport
- Added travel time to and from the Sounders vs. Timbers match Sunday, Aug. 27
- Added congestion on I-405 and state routes 167, 518 and 599
WSDOT contractor crews will close the SR 520 bridge between the Eastside and Seattle to prepare for the opening of the new westbound SR 520 lanes on Monday, Aug. 28.
- From 11 p.m. Friday, Aug. 25, to 5 a.m. Monday, Aug. 28, crews will close all lanes and ramps of:
- Westbound SR 520 between 92nd Avenue Northeast and Montlake Boulevard
- Eastbound SR 520 between I-5 and 92nd Avenue Northeast
