Highway

The total length of hard-surfaced highways constructed by the Romans has been estimated to be well over 50,000 miles (80,000 kilometres), much of which is still visible today after so many centuries.

Scottish engineer John McAdam (1756-1836) had become increasingly frustrated with highways that were often impassable because of rain and mud. He came up with a revolutionary method of road construction, which involved placing tightly packed layers of smaller stones bound with fine gravel on a base of large stones with adequate drainage to carry away rainfall. This macadamisation of roads did much to ease travel and communication and the process was quickly adopted in many other European countries and North America.

The initial section of the Lincoln Highway, the first automobile road across United States, was dedicated on December 13, 1913. It ran from Newark, New Jersey, to Jersey City, New Jersey.

In 1925 a group of state and federal highway officials began number highways with standardized road signs. Later, north-south highways were assigned odd numbers and east-west routes were given even numbers.


The Queen Elizabeth Way is a 400-Series highway in the Canadian province of Ontario, which begins at the Peace Bridge in Fort Erie and travels 86.4 miles around the western shore of Lake Ontario, ending at Highway 427. When it was initially opened in 1937, it was the first intercity divided highway in North America and featured the longest stretch of consistent illumination in the world.

The Pennsylvania Turnpike opened on October 1, 1940 between Irwin and Carlisle. It is considered to be the first superhighway in the United States, leading to the construction of other limited-access toll roads and the Interstate Highway System.

The Alaska Highway was constructed during World War II for the purpose of connecting the contiguous United States to Alaska through Canada. It was completed on October 28, 1942 at a length of approximately 1,700 miles.

The Trans-Canada Highway travels through all ten provinces of Canada between its Pacific Ocean and Atlantic Ocean. It is, along with the Trans-Siberian Highway and Australia's Highway 1, one of the world's longest national highways, with the main route spanning 8,030 kilometers (4,990 mi). The highway which officially opened on June 30, 1962, is recognizable by its distinctive white-on-green maple leaf route markers.

There are electric charging stations all along the Trans Canada Highway, making it the world's longest electric vehicle highway.

Highway 401 is a 400-series highway in Ontario stretching 508.2 miles (817.9 kilometres). The portion that passes through Toronto is the busiest highway in the world, and one of the widest (18 lanes pictured near Toronto Pearson International Airport).

The Pan-American Highway is listed in the Guinness Book of Records as the longest street in the world. It comprises a network of roads of 30,000 miles length from Prudhoe Bay, Alaska to Ushuaia, Argentina.

The longest US highway is route 6 which starts in Cape Cod, Massachusetts and ends in Bishop, California.

All the U.S. Interstate highways lined up would stretch about 47,000 miles—enough to circle the contiguous U.S. almost five times.


Highways in the western USA are based on the migratory routes of bison.

Southern Californians put a "the" before freeway numbers because Los Angeles had freeways with local names long before the rest of the country.

In Nevada it is illegal to ride a camel on the highway.
