Seattle traffic this weekend is going to bite

We are smack-dab in the middle of summer in Seattle, and that means there are a ton of events bringing in visitors by the hundreds of thousands.
This weekend, July 25-27, is the 40th annual Bite of Seattle at the Seattle Center. Over the years, attendance numbers have averaged near 355,000, with the highest recorded number at 406,000 visitors in 2006.
That’s an average of 120,000 daily visitors making the trek to Seattle during the three-day event, and that means a lot of traffic. Add to this, Revive I5 continues to block 2 northbound lanes of I-5 across the Ship Canal Bridge.
This, in itself, has proven to be more traffic than Seattle can handle, with daily backups taking drivers 40 minutes to drive 4 miles through downtown Seattle from the south. Drivers from the north have been dealt with nightmarish backups stretching 12 miles and adding over an hour to their commute.
Combine Revive I-5 with the Bite of Seattle and Seattle traffic — this weekend is going to bite.
Consider carpooling or riding public transportation. Sound Transit’s 1-Line is a good option, with easy access at Westlake Station to the Seattle Monorail that takes you directly to the Seattle Center.
Traffic outside of Seattle
The Washington State Department of Transportation (WSDOT) is keeping busy this weekend by shutting down 2 major highways and a section of I-5.
