Golden Gate Bridge to close for fireworks celebrating America's 250th. Here's what to know.

The Golden Gate Bridge will be closed on the evening of Saturday, July 4, as fireworks will be launched from the span to celebrate the country's 250th birthday.

Officials said that the historic display is only the third time that the bridge will be used for pyrotechnics, following similar displays celebrating the bridge's 50th and 75th anniversaries. Fireworks will be launched from the east side of the bridge between the towers, along with a barge off the bridge and a second barge near Pier 39.

The fireworks display is scheduled to begin at 9:30 p.m. The bridge will close to all traffic, including vehicles, pedestrians and bicycles, between 9 p.m. and 10 p.m.

"We are proud to join the City of San Francisco and regional partners in welcoming this Fourth of July celebration to the Golden Gate Bridge," Denis Mulligan, General Manager of the Golden Gate Bridge, Highway and Transportation District, said in a statement. "As stewards of this iconic structure and symbol of our community, we are honored to help celebrate our nation's 250th anniversary and look forward to a festive, safe, and memorable night for all."
