President Joe Biden is in Seattle on Thursday and Friday, and with his visit comes some temporary changes to transit service downtown and road closures, as well as likely congestion on nearby highways.

As Air Force One landed at Seattle-Tacoma International Airport at about 5:15 p.m. Thursday, roads and highways began closing in anticipation of Biden’s motorcade, snarling traffic on Interstate 5, Interstate 90 and Highway 520.

The Washington Department of Transportation would not confirm the precise timing and location of the closures. “For security reasons put in place by the Secret Service we can’t share those specifics,” the agency said on Twitter. Nevertheless, traffic maps showed long streaks of red heading into and out of Seattle.

Travel times were especially bad for those trying to travel north and south through Seattle. Where it normally take drivers 43 minutes to go from Alderwood to Southcenter, it was double that, at 87 minutes, Thursday evening.

WSDOT advised drivers to expect intermittent heavy congestion in the Seattle area Thursday evening and Friday due to temporary closures of the freeway system due to the president’s visit.

Sea-Tac Airport said passengers arriving at or departing from the airport should expect delays early Thursday evening with security protocols requiring all air traffic to stop for at least 30 minutes before arrival and shortly after.

Before Biden’s arrival, Seattle police and King County Metro blocked off partial access to downtown, with cruisers and buses spanning roadways to prevent motorists from driving on streets near the Westin hotel.

“Due to President Biden’s visit, King County Metro is advising travelers to allow extra travel time on Thursday, April 21, and Friday, April 22,” Metro said in a statement. “Some street closures will cause delays and disruptions to bus routes that travel in downtown Seattle.”

From Thursday to 4 p.m. Friday, bus stops between Jackson and Blanchard streets and Third and Ninth avenues could see temporary closures or relocations. Both Sound Transit and King County Metro announced changes to several routes Thursday.

Closures on parts of Westlake Avenue North, Denny Way, Fourth Avenue, and Lenora, Virginia and Pine streets will affect 12 Metro bus routes: 7, 40, 62, 64, 70, 216, 218, 257, 268, 311, 320 and the RapidRide C Line.

Riders can see how their route is affected by visiting Metro’s service advisories page.

The South Lake Union streetcar will not serve the Westlake Hub and will not travel south of Lenora Street. The platforms on Westlake Avenue at Olive Way and at Seventh Avenue stations will not be served.

Seattle Department of Transportation engineers will adjust the timing of traffic signals based on expected closures, the department said in a statement.

Sound Transit’s Link Light Rail will not be affected by Biden’s visit. But Sound Transit’s express routes 510, 545, 554, 577, 578, 590, 592 and 594 will all be rerouted on their routes through downtown. Buses will skip the following stops and riders should find a nearby alternative:
