Seattle Police will be out assisting with crowds and traffic in and around Gasworks Park in preparation for this year’s Family 4th at Lake Union. Between 45,000-50,000 are expected in the park.
The park will open at noon, and police will begin street closures in the neighborhoods north of the park from N. 40th Street and south to N. Northlake Way will close to all except motorists needing local access.
The Aurora Bridge will close to foot and bicycle traffic during the fireworks show. However, Metro buses will be providing free shuttles for pedestrians to get across the bridge. The bridge will remain open for motorists during the fireworks show.
At about 9 p.m., the Washington State Department of Transportation will begin closing the following:
- The southbound I-5 off-ramp to East Roanoke Street
- The Boylston Avenue East on-ramp to southbound I-5
- The southbound I-5 exit-only lane and off-ramp to Mercer Street
The closures will be complete by 10 p.m. The ramps and lane will reopen at the conclusion of the fireworks display.
The DOT, Washington State Patrol and the Seattle Police Department work together to help ease congestion and prevent drivers from stopping on I-5 to watch the fireworks by closing the ramps and lanes. The closures also provide troopers with a secure zone to work from as they monitor traffic and keep it flowing smoothly during the display.
SR 520 drawspan openings
The DOT says drivers should also keep in mind that July 4 is a very popular day for boating and the State Route 520 bridge drawspan will open with 1-2 hour prior notice. However, contractors working on the SR 520 replacement bridge have moved construction barges from the east navigational channel. Boaters with vessels up to 64 feet tall may use this channel and drawspan openings will be limited to boats 64 feet and taller.
