A massive bridge designed to be earthquake-proof is being constructed in the Chinese city of Shanghai before it is shipped to the US state of California.

The components will be pieced together between the northern California cities of Oakland and San Francisco.

The new structure will replace the ageing San Francisco Bay Bridge, from which a large piece collapsed in the 1989 earthquake but has since been rebuilt.

Many experts say the current bridge would not withstand another earthquake.
