The Seahawks will play the Philadelphia Eagles this evening, starting at 5:20 p.m. with an estimated attendance of 67,000 fans. Drivers can expect heavy congestion in the areas around the stadium, in the downtown area, and on major routes to the stadium (I-5 and I-90). The Airport Way South Viaduct over the Argo Rail Yard north of the Georgetown neighborhood is closed for construction, so this will not be an alternate route available for Seahawk traffic.  Seahawks fans are advised to arrive early. Commuters leaving the downtown area may want to also leave early, or wait to leave downtown until after kickoff.
