Big spend on road and rail across WA

Congested roads around Perth will benefit from $1.6 billion worth of road and rail projects across Western Australia, as Scott Morrison tries to woo voters in the west.

The prime minister will be in Perth for the second time this month to announce the funding on Thursday, days out from the federal budget.

Removing level crossings and improving the Fremantle Traffic Bridge are among key projects.

Mr Morrison has told The West Australian that along with easing congestion, the investments will better support regional areas and make roads safer, reducing trauma.

The commitment comes after the government committed $730 million to upgrading roads in north Queensland on Wednesday.
