The term “highway” may conjure images of an endless, unchanging road, dotted by the same fast food restaurants and gas stations every few miles.

But just as automakers have made endless variations of vehicles, road builders have come up with a lot of ways to get from here to there.

These eleven highways from all over the world are by turns high speed, beautiful, enormous, and deadly, and they are all worth a drive.

The Pan American is the longest motorway in the world.

First proposed in 1923, the Pan American Highway is the world’s longest highway system, stretching over roughly 16,000 miles.

Drivers who take on the entire route cross through 16 countries, including the United States, Mexico, Canada, Costa Rica, and Peru.

Highway 401 is the busiest in North America.

Highway 401, also known as the Macdonald-Cartier Freeway, is the busiest highway in North America. 420,000 vehicles drive on its 500 miles every day.

Since its completion in the 1960s, the highway has served drivers in the southern, central and eastern parts of Ontario, Canada.

The German autobahns are the fastest highways in the world.

Known as the fastest highway in the world, the German autobahns are motorways only for cars. In fact, bicycles, mopeds, pedestrians or any means of transportation unable to go faster than 38 mph, are prohibited from entering.

The nationally coordinated motorway for Germany, Bundesautobahn (BAB) translates to the federal way for cars. Although 52 percent of the BAB doesn’t have a speed limit,a top speed of 81 mph is recommended.

Due to the high speeds of most of the vehicles traveling on the autobahn, it is illegal to stop unnecessarily on the motorway — even if you run out of fuel.

The Trollstigen offers amazing mountain views.

Winding through the mountains of Norway, the Trollstigen, or Troll’s Path, is a popular tourist attraction for the views it affords of local waterfalls and the bridges that cross the rivers that feed them.

The road opened in 1936 after eight years of construction, and is closed between October and May, when winter weather makes it impassable.

The Guoliang Tunnel is carved into a mountain.

In China’s Taihang mountains, there is a 4,000-feet long road called the Guoliang Tunnel that was built by the villagers themselves.

In 1972, 13 villagers began the project to carve a road along the side of a mountain in order to link their village to the outside world. On May 1, 1977, the road was opened for travelers.

The Big Dig is the most expensive highway project.

Boston’s Big Dig was estimated to cost $2.8 billion in 1985 and soared to $14.8 billion, making it the most expensive highway project ever undertaken in history.

Beginning in 1991, construction for the Big Dig led to the fatal injuries of four workers and the death of a motorist, from the collapse of a concrete panel.

The expressway system was finally completed in 2007.

Yungas Road is the deadliest road ever built.

Barely ten feet wide, Bolivia’s Yungas Road kills an estimated 200 to 300 travelers each year, even though it’s shorter than 50 miles long.

Built by Paraguayan prisoners of war in the 1930s, the road leads from the city of La Paz to the Yungas region. It was deemed the most dangerous road in the world by the Inter American Development Bank in 1995.

The Katy Freeway is the widest in the world.

With 26 lanes in certain parts, the Katy Freeway, or Interstate 10, is the widest highway in the world. It serves more than 219,000 vehicles daily in Texas.

Built in the 1960s, Interstate 10 expands across a 23 mile stretch from its intersection with Interstate 610 to the city of Katy in Texas.

The Karakoram Highway is the highest paved highway in the world.

Running at 16,000 ft through the Himalaya, Karakoram, and Pamir Mountains, Karakoram Highway is the highest paved highway in the world. The Indus River also runs through some parts of the road.

In 1963, Pakistan and China signed an agreement to construct a road that would mutually benefit the two countries. In 1986, the Karakoram Highway officially opened to travelers and connected China with central Asian countries.

The highway runs 500 miles and connects the Xinjiang region of China with Islamabad, the capital of Pakistan.

Hong Kong’s Tuen Mun Road is known for high-volume accidents and being haunted.

Built in 1977 to connect the Chinese regions of Tuen Mon and Tsuen Wan, Hong Kong’s Tuen Mun Road is known for its high volume of accidents, and drivers place the blame on an usual suspect.

Some believe the Tuen Mun Road is haunted by the ghosts of those who have been killed while traveling it; according the local lore, they appear in the middle of traffic, sending cars veering out of control.

Or try a racing down roadway with no official speed limit at all.

There are only a handful of roadways in the world that have no speed limit at all.

Drivers go as fast as they want on highways in Nepal, the Isle of Man, and the states of Uttar Pradesh and Kerala in India.
