Long Island Roads

Home » Transportaion » Traffic » Roadways on Long Island

Long Island has an early history of roads and automobiles in America. Today, it can surely be said that Long Islanders are living up to this American legacy. There are 19 major highways on Long Island. The most travelled you can say are the major roads like the Long Island Expressway (LIE), Northern State Parkway, and Southern State Parkway. There’s so much ground to cover, totaling 1,377 square miles of land area. There's also the LIE running a significant width of Long Island and serving as a main artery. It’s no surprise that the LIE is a road heavily travelled on each day and known to be congested at all-times of the day that it has earned the recognition by locals as “The World’s Longest Parking Lot.” The following is a listing and brief description of the main roads and other highways.

Long Island's Major Highways & Expressways

Interstate 495/Long Island Expressway
I-495, commonly known as the Long Island Expressway or LIE, is Long Island's main freeway. It runs for 71 miles all the way from the Queens-Midtown Tunnel in Manhattan to County Route 56 in Riverhead, just before the forks split on LI's east end. Though it does not connect directly to its parent route, I-95, it is adjoined to the I-95 via I-295 in Queens.

The route was built in stages over the course of the mid-20th century with the first section, the Queens-Midtown Tunnel, opening to traffic in November of 1940. The last two miles between exit 71 and CR 58 were completed in June of 1972. HOV lanes were later added and now run from exit 31 to exit 64.

Long Island's Major Parkways

Bethpage Parkway
The Bethpage Parkway is just under two and a half miles long and connects the Southern State Parkway with Bethpage State Park.  As it is a park of the State Parkway system, commercial traffic is not permitted.  This road travels North and South through Nassau County.

Meadowbrook Parkway
The Meadowbrook Parkway is part of the State Parkway system, serving as an alternate route to Jones Beach. It travels North and South through Nassau County and no commercial traffic is permitted on this road.

Northern State Parkway
Also referred to as Northern Parkway or simply the Northern State, this limited-access state parkway connects Northern Suffolk County with Nassau and Queens. It stretches just under 29 miles long and runs from the border of Nassau and Queens to Hauppauge. In western Nassau the parkway contains three lanes of traffic in each direction, but it narrows to two near exit 33.

Construction on the Northern State occurred in stages from the 1930s through 1965, when its current end in Hauppauge was finished. The Northern State does not actually end in Queens, but instead changes names to the Grand Central Parkway. Commercial truck traffic is not permitted on the Northern State due to low overpasses.
