To make our travel life easier we build various streets and roads. Among those roads and streets there are peculiar which everyone should know about to liberalize.

The shortest street

Ebenezer Place, in Wick, Caithness, Scotland, is credited as being the world’s shortest street in the Guinness Book of Records at 2.06 m (6.8 ft). There is a single address on the street, 1 Ebenezer Place, which was constructed in 1883. The owner of the building, a hotel at the time, was instructed to paint a name on the shortest side of the hotel. It was officially declared a street in 1887.

The longest street

The Pan-American Highway is a network of roads nearly 48,000 kilometers (29,800 miles) in total length. Except for an 87 kilometers (54 mi) rainforest gap, called the Darién Gap, the road links the mainland nations of the Americas in a connected highway system. According to Guinness World Records, the Pan-American Highway is the world’s longest "memorable road". However, because of the Darién Gap, it is not possible to cross between South America and Central America by traditional motor vehicle. The Pan-American Highway system is mostly complete and extends from Prudhoe Bay, Alaska, in North America to the lower reaches of South America. The Pan-American Highway travels through 15 countries: Canada (unofficially), United States (unofficially), Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, Chile, Argentina.

The narrowest street

Parliament Street is a 50m long street in Exeter, England, which links the High Street to Waterbeer Lane and dates from the 14th century. It was formerly called Small Lane and was renamed when Parliament was derided by the city council for passing the 1832 Reform Bill. The street is approximately 1.2m (45") at its widest and less than 0.64m (25") at its narrowest, making it the world’s narrowest street. Two people cannot easily pass in Parliament Street.

The widest road

Avenida 9 de Julio is an avenue in Buenos Aires, Argentina. Its name honors Argentina’s Independence Day. The avenue has six lanes in each direction. The avenue’s unusual width is due to the fact that it spans an entire city block, the distance between two streets in the checkerboard pattern used in Buenos Aires. The distance between adjacent streets is roughly 110 meters, greater than the equivalent distance in Manhattan, New York, USA.

The most winding street

Lombard Street is an east-west street in San Francisco, California. It is famous for having a steep, one-block section that consists of tight hairpin turns. Lombard Street is best known for the one way section on Russian Hill between Hyde and Leavenworth Streets, in which the roadway has eight sharp turns (or switchbacks) that have earned the street the distinction of being "the crookedest [most winding] street in world."
The switchbacks design, first suggested by property owner Carl Henry and instituted in 1922, was born out of necessity in order to reduce the hill’s natural 27% grade, which was too steep for most vehicles to climb and a serious hazard to pedestrians used to a more reasonable sixteen-degree incline. The crooked section of the street, which is about 1/4 mile (400 m) long, is reserved for one-way traffic traveling east (downhill) and is paved with red bricks. The speed limit here is a mere 5 mph (8 km/h).

The most complicate roundabout

Swindon, England is notable for its roundabouts and there is even a calendar featuring a different roundabout each month. The best-known roundabout is the ‘Magic Roundabout’, which is actually not a roundabout but a gyratory. The Magic Roundabout was constructed in 1972 and consists of one large roundabout containing five mini-roundabouts. It is located near the County Ground, home of Swindon Town F.C. Its name comes from the popular children’s television series The Magic Roundabout. Traffic flow around the smaller, inner roundabout is anticlockwise, and traffic flows in the usual clockwise manner around the five mini-roundabouts and the outer loop.

The steepest street

Baldwin Street, in a suburban part of New Zealand’s southern city of Dunedin, is reputed to be the world’s steepest street. It is located in the suburb of North East Valley, 3.5 kilometers northeast of Dunedin’s city centre. A short straight street of some 350 meters length, Baldwin Street runs east from the valley of the Lindsay Creek up the side of Signal Hill. Its lower reaches are of only moderate steepness, and the surface is asphalt, but the upper reaches of this cul-de-sac are far steeper, and surfaced in concrete, for ease of maintenance (tar seal would flow down the slope on a warm day) and for safety in Dunedin’s frosty winters. At its maximum, the slope of Baldwin Street is approximately 1:2.86 (19° or 35%) – that is, for every 2.86 meters traveled horizontally, the elevation rises by 1 meters.
The street’s steepness was unintentional. As with many other parts of Dunedin, and indeed New Zealand, streets were laid out in a grid pattern with no consideration for the terrain, usually by planners in London.
