Well, the New Jersey Turnpike Authority is taking no chances and, with $7 million from the U.S. Department of Homeland Security, is now in the process of installing thousands of feet of high-security fencing around 10 major bridges along the Parkway and the Turnpike.
"It's part of our ongoing efforts to make our highway system as safe and secure for our motorists as possible," Ronnie Hakim of the NJ Turnpike Authority.
So will an 8-foot chain link fence protect this bridge and the others from terrorists?
"I know in Seattle they have covered most of the bridges for that reason," Ruth Hallowell of Dorothy, NJ said.
But most of those we asked have their doubts about a fence doing anything to stop someone who wants to harm.
"Let's see. A terrorist could drive up on the bridge and blow it up from the top or they could come under the bridge with a boat and blow it up. What's that fence going to stop?" Fred Schaefer of Upper Township, New Jersey said.
"What is it going to do? So I think it's a waste of time and money," David Harrison of North Cape May County said.
You might not think Cape May County is a hotbed of terrorism, but apparently some bombers and hijackers like spending time at the shore.
One of the men convicted in the 1993 bombing of the World Trade Center was arrested by the FBI at the former Sea Wolf Apartments in North Wildwood and Marwan Al-Shehhi, who flew United flight 175 into the Twin Towers in 2001, reportedly visited the Wildwood boardwalk and also checked in to taking flying lessons at the Cape May County Airport.
There have been threats to bridges in New York and authorities in Cape May County say while it may not be foolproof, they hope fencing will help discourage anyone looking to damage them.
