Hoboken officials are asking anyone planning to visit the city on the Fourth of July to make a plan before heading out, warning that this year's holiday could bring some of the largest crowds the city has ever seen.

With Fourth of July fireworks, Sail250 celebrations and events taking place across the Hudson River, city leaders expect thousands of visitors to flock to Hoboken's waterfront.

To avoid the gridlock seen during past celebrations, Hoboken's Office of Emergency Management is rolling out an extensive traffic and public safety plan.

"We do have two years ago in our minds," Mayor Emily Jabbour said. "It was six hours of gridlock, and it just wasn't safe for our public safety divisions. It was really a challenge."

Beginning as early as 8 a.m. on July 4, police will begin restricting vehicle access into the city.

According to Public Safety Director Ken Ferrante, residents, people with reserved parking in designated garages, employees working in Hoboken, rideshare vehicles and public transit will still be allowed into the city. Drivers attempting to use Hoboken as a shortcut or looking for a place to park and watch the fireworks will be turned away at entry points.

Officials are strongly encouraging visitors to use public transportation whenever possible. Those who must drive are urged to reserve a parking spot in one of the city's municipal garages before arriving.

Several streets will also be closed throughout the holiday, and Pier C, the Sgt. William Feskens Little League Field and Sinatra Park Soccer Field will be closed to the public.

City officials say there will be zero tolerance for anyone who ignores the restrictions, and they're encouraging everyone to plan ahead to help keep traffic moving and ensure emergency crews can respond if needed.
