SODO Traffic Alert: Weekend Traffic Warnings!

Stadium traffic on Saturday

Traffic is expected to be particularly ugly on Saturday in the SODO area when the U of W holds its graduation ceremonies at CenturyLink Field with gates opening at 12 noon and the ceremonies wrapping up around 4:30 p.m., or later, and the Seattle Mariners taking on the LA Dodgers next door at Safeco Field starting at 4:15 p.m.  Parking has been reserved for the use of Mariners baseball fans only at four nearby garages; advise from the Mariners’ headquarters is that Saturday’s game attendees pre-purchase their parking on-line.
