It’s impossible to drive from North to South America because there are no roads between Panama and Colombia.
Children who live near major roads are more likely to have developmental delays. Research found that living closer to a major roadway such as an interstate highway or a state highway is associated with almost two times the risk of having a communication delay by the time the baby is 3 years old.
22-yr-old Canadian man John McCue took it upon himself to fill potholes with the sign: “I filled the potholes. Pay me instead of your taxes.” Drivers gave him cash, coffee and joints for filling in potholes.

A 106-mile portion of I-70 in Utah has no gasoline or exits. It is the longest portion of the US Interstate system without services. A station at one end sells about 30 gas containers a week to people who run out on the highway and walk to the station.
A Japanese engineer by the name of Shizuo Shinoda accidentally scraped some markings into a road with a bulldozer and drove over them, and realized that it was possible to create tunes depending on the depth and spacing of the grooves. In 2007, the Hokkaido National Industrial Research Institute refined Shinoda’s designs to create the Melody Road. They used the same concept of cutting grooves into the concrete at specific intervals and found the closer the grooves are, the higher the pitch of the sound; while grooves which are spaced farther apart create lower pitched sounds. Today, musical roads are known to exist in six countries: Denmark, Japan, South Korea, the United States of America, Mexico and San Marino.
10,000 Iowan farmers built 380 miles of road (entire width of the state) in one hour on a Saturday morning in 1910.

The first known musical road, the Asphaltophone, was created in October 1995 in Denmark, by two Danish artists.
