ParkingDon't expect to drive anywhere near the parade route and easily find parking; it will be very limited. The Lumen Field parking garage and north lot will be closed. Paid event-day parking will be available in some lots surrounding the stadium, but you'll likely have to pay a premium rate for a spot.Road closuresAll northbound lanes of 4th Ave will be closed from S Jackson St to Denny Way. Also expect road closures on streets that intersect with 4th Ave between Lumen Field and Seattle Center between 11 a.m. and 1:30 p.m. Congestion is expected along surrounding side streets. On and off ramps to Interstate 5 and Interstate 90 will be held briefly at the start of the parade, but will open shortly after.Streets are supposed to begin reopening starting around 1:30 p.m.When and where does the parade end?The parade ends at the intersection of 4th Ave and Cedar Street. The two-mile route through downtown Seattle is expected to take two hours, so the parade is estimated to end around 1 or 1:30 p.m.There is no post-parade event at Seattle Center, as the Trophy Celebration is held at Lumen Field ahead of the parade.What about safety?A Seattle Police Department spokesperson said the route would be secured and the department would be calling in as many officers and mutual aid partners as possible. Police said their largest concern is checking the temperament of the crowd and managing the huge number of people in a fairly small space."We're going to have just about everyone we can get. We're expecting great crowds. So we want to make sure it's safe for everybody," said Capt. Marc Garthgreen, Commander of the West Precinct. "We'll have officers all along the route. You'll see them in their high-vis yellow vests. That way, officers and citizens can find them easily in case of any need or questions that may arise."Additionally, police said that in previous years, guns have been stolen out of cars, so firearm owners should leave their guns at home.When asked about hypothetical mass shootings or terrorist events, the SPD said multi-agency situation training and tactics would be used in preventative and active ways.Police also stated that plans are in place to accommodate potential interruptions by protesters.Going to the parade?
