From Linda Thielke at King County Department of Transportation:

The Seattle Sounders soccer team will open up the post season with a playoff game against the Houston Dynamo on Thursday at 7 p.m. at Qwest Field.

The game could disrupt traffic as thousands of fans in green-and-blue scarves are expected to descend on Pioneer Square and the Sodo area. Expect traffic congestion during the afternoon and evening commute. Also, bus passengers who are traveling through the downtown area Thursday afternoon may experience some delays in transit service.

For fans wanting to beat the traffic and travel to the game by bus, use Metro Transit’s Trip Planner to plan a route most convenient for you. And, West Seattle Water Taxi passengers should be aware the Water Taxi will operate a Friday night schedule on game night, with the last sailing from Seattle to West Seattle at 10:30 p.m.

And a reminder, Saturday is the last day of the season for the Water Taxi – which is scheduled (pending election and budget variables) to go into year-round operation after Seacrest dock improvements are done early next year.
