Question:

least a 6.0 earthquake

Answers:

new driver question?

It's called civil engineering...you need to determine your safety factor and work from that to find the best stress the bridge can handle. Once you have the stress you can use that to find an ideal material and using that you can figure out a good structure. For example, a wooden bridge cannot be as high or wide as a steel reinforced concrete bridge. If you are working on the project you should have an engineering background. as for bridges that can withstand earthquakes, take a look at San Francisco bridges!
