Big fire at the Los Angeles Motorshow in 1929.
The Kawazu-Nanadaru Loop Bridge, in Japan, is an example of how to build a bridge from one mountainside to another when the sides of the mountain are so steep that it is not possible to build a road at the same elevation on both sides. It's one of the most spectacular bridges in the world.
This double spiral brings cars up and down a full 45 meters (148 feet) while being seemingly suspended in a valley between two mountainsides.
Some other stats:
- 1.1 km long
- 80 meters in diameter
- speed limit: 30 km/h (19 MPH!!!!) I wonder what the record speed is?
That is accurate!
