Westbound SW Spokane St at E Marginal Way and the off- ramps to Harbor Island from westbound West Seattle Freeway and from southbound SR99 will be closed this coming weekend beginning Friday evening, October 21, at 7 p.m. The roadway and off-ramps will reopen Monday October 24, by 5 a.m. This work was rescheduled from last weekend due to rain. The closures are needed to remove an abandoned railroad track crossing and to perform pavement repairs on SW Spokane St.
· Motorists who are not in large trucks/commercial vehicles can detour by taking the high level West Seattle Bridge, using the Delridge Way exit, then taking the right onto Chelan Ave SW, another right onto SW Spokane St, and eastbound across the Duwamish West Waterway and back onto Harbor Island.
