New York City: Bridges & Tunnels
Welcome to our bridges and tunnels page. There are about nine entries and exit points how to get in and out on Long Island. Below are detailed information and reference that we’ve specially made on these bridges and tunnels.
Most people considered the very first bridge (made by nature) as simple as a fallen log that crossed a river in which people and even animals could pass through. Later, people had the idea to improve these structures by using spans of wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Most of these early bridges could not support heavy weights or withstand strong currents. It was these inadequacies which led to the development of better bridges. The ancient Romans were the first people to built arch bridges and aqueducts, in some of which still stand today. These arch based bridges could stand in conditions that would damage or destroy more primitive designs. Today, there are about six main types of bridges such as beam bridges, cantilever bridges, arch bridges, suspension bridges, cable-stayed bridges, and truss bridges.

For water crossings, a tunnel is generally more costly to construct than a bridge. Navigational considerations may limit the use of high bridges or drawbridge spans intersecting with shipping channels, necessitating a tunnel. It was originally a hand-dug structure by several ancient civilizations in the Indian and Mediterranean regions. In addition to digging tools and copper rock saws, fire was sometimes used to heat a rock obstruction before dousing it with water to crack it apart.
The Brooklyn Bridge is among of the oldest suspension bridges in the United States that stretches 5,989 feet over the East River connecting both boroughs of Manhattan and Brooklyn in New York City.
Tunnels are relatively in small-diameter which carry utility lines or function as pipelines. They are basically used to transport people by rail or by automobile often comprising of two or three large, parallel passages for opposite-direction traffic, service vehicles, and emergency exit routes. In comparison to bridges, tunnels (water-crossing) has an advantage in minimizing difficulties with tides, weather and shipping during construction, aesthetic reasons, and also for weight capacity reasons. As for bridges, they usually require a larger footprint on each shore than tunnels.
