Qld road projects get $415m funding boost

New road projects and safety upgrades in Queensland will receive a $415 million cash injection in a bid to stimulate the economy.

The federal and state governments will jointly fund 14 shovel-ready projects expected to support 700 jobs.

Prime Minister Scott Morrison said infrastructure investment would form a central plank of the economic recovery.

"Infrastructure will be a key to jobs as we grow out of the COVID-19 recession," he told reporters in Sydney on Monday.

The federal government will bring forward $325 million from its recently announced $1.5 billion infrastructure fund while Queensland will contribute $90 million.

Projects in the NT will have $53 million pumped into them, and roads in the ACT will get $35 million in funding brought forward.

The commonwealth will also put $176 million towards $223 million worth of projects in WA.
