World's Narrowest Street (Spreuerhofstraße – Germany)
Most Complicated Interchange (Judge Harry Pregerson Interchange – Los Angeles)
World's Longest National Highway (Highway 1 – Australia)
World's Largest Roundabout (Putrajaya – Malaysia)
The main reason people don't take note is because they tend to think it is just a hill. The circumferential length of this roundabout is approximately 3.4km, and the road that circumvents it is Persiaran Sultan Salahuddin Abdul Aziz Shah.
World's Widest Street (9 de Julio – Buenos Aires, Argentina)
Those with a quick pace and long legs will be lucky if they get to the other side with the changing of two traffic lights that are placed at every intersection. A pedestrian crossing usually requires a few extra minutes and a few green lights. However, the inevitable stop in the center provides a great perspective of the magnitude of the street as well as the city. The street runs far in both directions and connects the unique sections of the great metropolis. Some of Buenos Aires' main landmarks can be seen along the way; most notably, the Obelisk.
World's Longest Street (Yonge St – Ontario, Canada)
(Actually, The Guinness Book of World Records no longer lists Yonge as the longest street in the world, citing instead the Pan-American Highway as the world's longest "motorable road").
