What are interstate highways?

President Dwight D. Eisenhower signed the Federal-Aid Highway Act of 1956, which established the system of interstate highways in the United States. Interstate highways are federally funded freeways that allow the rapid transportation of people, goods, and the military across the country.

Why was Eisenhower a fan of interstate highways?

In 1919, the young Dwight D. Eisenhower took part in a cross-country military trip from Washington, D.C., to San Francisco. But, due to the state of the highways at that time, the trip took 62 days—far too long to defend the country should the need arise. This experience made Eisenhower realize the need for a faster, more efficient mode of transportation across the country. Because of President Eisenhower's support for the Interstate Highway System, it is now officially known as the Dwight D. Eisenhower System of Interstate and Defense Highways.

What is the Chunnel?

The Channel Tunnel (or Chunnel) is a railroad tunnel under the Strait of Dover in the English Channel.

The Panama Canal is a remarkable achievement in engineering. Completed in 1914 and costing the lives of over 27,000 workers, the canal cuts shipping routes in half.

doors close in front of and behind it. Water is then added or drained from the area to raise or lower the ship to a different elevation. Then the doors in front of the ship open and the ship sails down the canal to the next lock or to the open sea.

In which direction do ships sail through the Panama Canal?

Though you would expect them to travel east from the Pacific to the Atlantic Ocean when sailing through the Panama Canal, ships actually travel northwest. Since the Isthmus of Panama lies parallel to the equator, the canal does not lie east-west but rather northwest-southeast.

Why was the Erie Canal built?

The 363-mile (584-kilometer) Erie Canal connects the Hudson River to Lake Erie. Opened in 1825, the canal created a new, shorter route from the northern interior of the United States to the Atlantic Ocean. Prior to the opening of the Erie Canal, goods traveled down the Mississippi River and out to the Atlantic. Since New York City lies on the Hudson River, the canal was responsible for the growth of the city as a major port, helping it to become the largest city in the United States. Once the St. Lawrence

Seaway was built in 1959, the Erie Canal became rarely used, since most transportation soon traveled along the Seaway.

What is the St. Lawrence Seaway?

Completed in 1959, the 183-mile (294-kilometer)-long St. Lawrence Seaway was built by deepening and widening the St. Lawrence River between Montreal, Canada, and Lake Ontario so that large ships could traverse it. The Seaway consists of a series of locks that allow ships to travel from the Atlantic Ocean to the Great Lakes, and ultimately on to Chicago. A limiting factor of the Seaway is that ships can only use the Seaway between May and November, as it is blocked by ice in the winter.
