Western Sydney motorists will be the winners of a new $1 billion state government roads package.
The funds will go towards upgrades, safety improvements and a new bypass.
Part of the new builds are to improve evacuation routes in the wake of the last two years of flooding which have left residents stranded at times or struggling to flee rising water.
"It's not just safety," Premier Dominic Perrottet said on Sunday as he announced the funding.
"These roads will make a difference to people's lives."
From the $1 billion, $200 million will go to safety improvements along parts of Elizabeth Drive in Kemps Creek.
Another $100 million will see the Pitt Town Bypass built to help with flood evacuations.
Garfield Road East in Riverstone and Box Hill will be expanded to a four-lane divided road, which will also help with flood evacuations, at the cost of $100 million.
The remaining $600 million will be delivered to 15 of local government areas that are yet to be determined.
