With Philadelphia’s Fourth of July festivities for the United States’ 250th birthday having come and gone, this weekend will mark a celebration for a newly minted centenarian. And with any luck, that party won’t run so late.

Technically, the Benjamin Franklin Bridge turned 100 on July 1, but the Delaware River Port Authority will mark that milestone with a party Saturday.

Set to take place from 10 a.m. to 2:30 p.m. on the Camden side of the bridge near its toll plaza, the event will close the bridge to vehicles for much of the day, allowing attendees to walk the span’s roadway.

The party will feature interactive historical displays, food trucks, music, and other activities. It’s open to the public and free to attend, and while not required, advance registration via the DRPA website is encouraged, officials said.

“For 100 years, the Ben Franklin Bridge has stood as more than a crossing over the Delaware River. It is a public promise,” John T. Hanson, DRPA chief executive officer, said in a statement. “We are proud to invite the public to celebrate its past, recognize those who have preserved it, and look ahead to the next 100 years.”

Here is what you need to know:

Closed to cars

Due to the event, the bridge will be closed to vehicular traffic in both directions from 8:30 a.m. to 4 p.m. Saturday, DRPA officials said in a statement.

Road closures around the Benjamin Franklin Bridge, officials said, should be expected during the event. However, the Walt Whitman and Betsy Ross Bridges will remain open for motorists.

While the bridge travel lanes will be open to foot traffic, the pedestrian walkway will be closed during the event. It will reopen at 2:30 p.m., and continue to operating until 9 p.m., the usual closing time.

Additionally, PATCO trains will continue to operate across the bridge Saturday, with enhanced service instituted to allow trains to run every 15 minutes throughout the bridge celebration.

How to get there

For those looking to get to the Camden side’s main party area, DRPA officials advise using the PATCO option from Philadelphia, which can get you to Camden’s City Hall station nearby.

There will also be a complimentary shuttle service operating continuously throughout the event. One shuttle route runs between the Camden City Hall station and the event entrance, and another from PATCO’s Franklin Square Station at 7th and Race Streets in Philly to the event site in Camden, DRPA spokesperson Mike Williams said.

And, of course, from Philly, you could just get to the Jersey side by walking across the bridge. Starting from the main event area in Camden is not required

“The bridge walk is really the centerpiece of the celebration, and we hope attendees take advantage of this rare opportunity,” Williams said.

Bikes are permitted on the roadway but are not permitted in the main party area.

For those who plan on driving, parking areas will be available on the Jersey side. They include free lots at Rutgers University, on-street metered parking, and a paid parking garage at Camden Technology Center, DRPA said.

What if it rains?

Saturday’s event will go on rain or shine, and there is no rain date, Williams said.

Officials had announced a rain date of July 12, but the event logistics made a rain date impractical, Williams said.

Things to do

In addition to the food trucks and vendors, the event will feature dance performances and special guests.

A “Winged Victory” statue, one of four that originally sat atop the bridge at its opening in 1926, will also be on display.

A family fun zone will offer an inflatable obstacle course and oversized yard games, as well as face painting and other entertainment, organizers said. And attendees will also be able to get up-close views of the vehicles that work on the bridge, such as a barrier mover known as a “zipper machine,” as well as front-end loaders, and dump trucks.
