The Long Island Expressway (LIE) is one of the interstate highways with the designation of Interstate 495. It runs 66.38 miles (106.8 km) from New York City, New York the length of Long Island, Nassau and Suffolk counties, ending just before the "fish-tail" (where the island splits into northern and southern forks) at Riverhead, New York.
Smaller highways continue on from the end of the LIE to Greenport on the North Fork and past the Hamptons to Montauk on the South Fork. Cynics have suggested that the acronym is appropriate, in that the term "expressway" is a lie.
In 1999, an HOV lane was added in each direction from Deer Park to (near) Hicksville. Construction to extend the lane to the border of Queens and Nassau Counties is underway and to be finished by May2005.
Originally, I-495 was to stretch from the Queens Midtown Tunnel and I-278 to I-295, the Clearview Expressway. Plans later included creating the Mid-Manhattan Expressway across Manhattan to the Lincoln Tunnel, to connect to I-95 in New Jersey. These plans were eventually cancelled, and the NJ stretch of I-495 was downgraded to a NJ state highway. However, Long Island lobbied to extend I-495 east, upgrading NY 24 to NY 495 and then I-495, to Riverhead where it terminates at NY 25. Since I-495 extends from a city outward, it is technically a spur, which should have an odd first digit. Even first digits are usually assigned to bypasses and beltways. A proposed Long Island Crossing bridge could connect I-495 with the mainland in Connecticut or Rhode Island, where it could link to I-95, making it a bypass instead of a spur.
LongIsland is connected to the mainland and the other island boroughs by a ribbon of vehicular bridges that cross the East River, the Verrazano Narrows Bridge (which connects to Staten Island), and several tunnels carrying motor vehicles and trains.
LongIsland has a climate that is very similar to other coastal areas of the Northeastern United States; it has warm, humid summers and cold winters, but the Atlantic Ocean helps bring afternoon sea breezes that temper the heat in the warmer months and limit the frequency and severity of thunderstorms.
In sequence from shallowest to deepest, the LongIsland aquifers are: the Upper Glacial, the Magothy and the Lloyd Aquifers.
