Oh well.
The bridge is a very impressive structure and is one of the largest suspension bridges in existence. The towers are nearly 300 meters tall (nearly 1000 ft) and nearly 4km long (about 2.5 miles). It was built after a couple of ferries sank and 150 lives were lost, mostly schoolchildren I believe.
If you click on the bridge data picture it will expand and you can read the detail.
The toll to cross is about $50 (covers out and back).
The bridge had to be designed for an earthquake prone zone and was under construction when the 1995 Kobe earthquake occurred. They ultimately discovered that the towers had shifted during the quake and they had to start over with at least one of the structures.
The suspension cables are 1.1 meters thick (maybe 45 inches) and consist of multiple hexagonal strands that are designed to be fairly rigid in one direction and flexible in the other.

You can feel the bridge move with traffic and this would be important in an earthquake. Equally the bridge has to be designed to sustain and survive high winds. So It is a complex structure that was expensive to build but manages the task while also being a beautiful (in my mind anyway) piece of architecture.
