Transportation in New York City City and Fort Lee, New Jersey, is the world's busiest bridge in terms of vehicular traffic. New York has historically been a pioneer in tunnel construction. Most carry rail lines, but there are four exceptions. The Lincoln Tunnel, which carries 120,000 vehicles per day under the Hudson River between New Jersey and Manhattan, is the world's busiest vehicular tunnel. The Holland Tunnel, also under the Hudson River, was the first mechanically ventilated vehicular tunnel in the world and is considered a National Civil Engineering Landmark by the American Society of Civil Engineers. Two other notable tunnels connect Manhattan to other
Union City, New Jersey the New Jersey Meadowlands. The city is bisected by New Jersey Route 495, a vehicular cut built in conjunction with the Lincoln Tunnel. Soon after its construction, many street names were abandoned in favor of numbering in most of North Hudson starting at 2nd Street, just north of Paterson Plank Road, which runs through the city's only major park and creates its border with Jersey City. 49th Street is the northern boundary with West New York. Apart from a small section between Bergen Turnpike and Weehawken Cemetery, Kennedy Boulevard, a major north-south thoroughfare, creates the western border with North Bergen.
