Traffic Alert: Trans-Siberian Orchestra & Seattle Marathon will impact traffic this weekend

Posted on November 28th, 2015 by Laura Fonda


Two traffic alerts for today and tomorrow – Trans-Siberian Orchestra is at Key Arena today, Saturday, for performances at 4pm and 8pm. The city estimates 10,000 people will attend each of the shows (20,000 total), so expect traffic around Key Arena this afternoon and evening.

The bigger impact will likely be from the Seattle Marathon, which is tomorrow, Sunday, November 29th. The organizers cite the Seattle Marathon as the “largest combination marathon/half marathon in the Northwest and one of the top ten largest in the US” – what does that mean? 15,000 participants + thousands of spectators, and road closures around the Seattle Center, where the race starts and finishes.

The race map with street closures is below. For some reason, the Seattle Marathon organizers have once again decided to produce a West-oriented map, instead of the standard North-oriented view. So, it may look a bit odd, but note that 5th Ave near the Seattle Center will be closed 5:30am-9am, and one side of Mercer will be closed 8:45am-4pm.

And, just to make things a bit more complicated, traffic-wise, the Seahawks are playing the Pittsburgh Steelers at CenturyLink tomorrow (Sunday), with kickoff at 1:25pm.
