The start of fall typically means highway construction projects begin wrapping up for the winter. That includes I-5 construction work south of Seattle, with just two remaining weekend-long lane closures on northbound Interstate 5 in Tukwila.
The interstate will be reduced to two lanes north of the I-5/I-405/State Route 518 interchange from Friday, September 29, to Monday, October 2, and Friday, October 13, to Monday, October16. Drivers need to plan for lane closures starting at 8:00 p.m. each Friday, with all lanes reopened by 5:00 a.m. each Monday. The work is weather dependent.
During the weekend of September 29 to October 2, contractor crews working for the Washington State Department of Transportation will replace expansion joints in the left lanes of northbound I-5 at the Duwamish River. People driving should plan ahead for the following:
The northbound I-5 HOV bypass lane will be closed. The on-ramp from eastbound SR 518 to northbound I-5 will remain open, but drivers will need to merge right almost immediately. Both lanes exiting to SR 599 will remain open, providing an alternative route into Seattle.
