The state has just laid out its plan for major summertime road work, and that includes Highway 99 just north of West Seattle. First, a busy weekend of regional work will include a shutdown of southbound 99 between Denny Way and the WS Bridge, 10 pm Friday, June 6, until (no later than) 5 am Monday, June 9. This, WSDOT says, is “to shift southbound traffic onto a new route through the State Route 99 tunnel project site.” That same weekend, two lanes of northbound I-5 will be closed just north of the WS Bridge for more expansion-joint work, and the 520 Bridge across Lake Washington will be closed, so that first weekend of June might be a great time to just not try to leave the peninsula.
WSDOT also has announced Highway 99 work that will include nighttime closures in the late summer:
This project will replace 81 concrete panels on the aged stretch of Highway 99 in the area shown above, between the West Seattle Bridge and the remaining elevated Alaskan Way Viaduct. From the project webpage:
In summer 2014, contractor crews will repair 81 concrete panels in both directions of State Route 99, between South Spokane and South Holgate streets in Seattle’s SODO neighborhood. Crews also will grind down 198,000 square feet, approximately three and a half football fields, of wheel ruts. This project is similar to concrete grinding and replacement work we have done on I-5 in Kent, Seattle near the Ship Canal Bridge, and I-405 near Bellevue.
What can drivers expect?
• Weekend and weeknight lane closures in both directions of SR 99 between South Spokane and South Holgate streets
Right now, that work is not expected to start until August. Watch our weekday traffic coverage for reminders about upcoming projects as well as day-to-day updates.
