West Seattleites are getting a nice preview of what life will be like once the viaduct is toppled, as an accident this morning on northbound 99 has apparently necessitated the closure of two lanes. A close friend of mine left her home near the Delridge Home Depot around 7:45, and had made it as far as Harbor Island in a half hour’s time. Unfortunately, this isn’t the sort of situation more buses can help remedy. West Seattle will need its own trolley line with dedicated right of way, a fleet of foot ferries from Alki that set sail every 15 minutes or, better yet, both, once V-Day arrives in 2012.
