In short:

The Fremantle Traffic Bridge will shut for up to 12 months from February 1 so it can be demolished and replaced.

Treasurer Rita Saffioti says she is confident of being able to limit the closure to just that year or possibly less.

Transport authorities expect significant delays for motorists entering and exiting Fremantle across the Swan River.
