Drivers are being advised to delay any "non-essential" trips while Biden is in town.

Vice President Joe Biden is visiting Seattle today, which means the highways he travels on will close.

Biden landed at Boeing Field and headed to the annual Golden Tennis Shoe luncheon and fundraiser put on by U.S. Sen. Patty Murray, who is up for re-election this year. He also visited the Fred Hutchinson Cancer Research Center to speak about the Obama administration’s $1 billion cancer “moonshot” effort, tour a lab and participate in a cancer-research discussion.

Here’s what we know about traffic impacts as they stand now:

  • All state highways were open as of about 2:30 p.m.
  • The state Department of Transportation blacked out some traffic cameras, which is a standard security precaution directed by the Secret Service whenever dignitaries visit.
  • The Secret Service does not reveal a motorcade’s exact route ahead of time, which makes it tough to predict which roads will be closed.
  • Bottom line, WSDOT said: Avoid taking “non-essential” trips while the veep’s in town, and if you have to drive, leave yourself extra time. Same goes for Hillary Clinton’s visit tomorrow.

As of around 5:30 p.m., Biden’s motorcade was in South Lake Union, where the Vice President reportedly ordered takeout pizza. Then, the motorcade started heading from downtown Seattle to Boeing Field on southbound Interstate 5.

Seattle’s department of transportation on Twitter said crews temporarily closed the interstate at Mercer Street, causing long delays and backups. The department warned evening commuters of heavy congestion, though the stretch opened about 10 minutes after closing.


Biden last visited the state in 2014 for a tour of Renton Technical College and a political fundraiser for U.S. Sen. Maria Cantwell.
