The Victorian government says it's improving freight connections across the state by expanding the High Productivity Freight Vehicle (HPFV) network.
The government said the upgrades would save farmers, freight operators and businesses time and money and further encourage freight operators to invest in newer, safer and cleaner vehicles.
Around 3,000 kilometres of road have been added to the pre-approved HPFV network, reducing costs and saving time by eliminating the need for individual route assessments.
"These upgrades will deliver stronger, safer and more reliable roads for the freight industry - meaning farmers and suppliers will be able to get their goods to market much more efficiently," Roads Minister Ben Carroll said.
"Improving the network will take trucks off local roads - backing local jobs and making our country roads safer."
The new networks will be published online and include key freight routes along the Bass Highway, Murray Valley Highway, Wimmera Highway and Ballarat-Maryborough Road.
Mr Carroll said High Productivity Freight Vehicles were safer and more efficient modern vehicles that will reduce the number of truck trips needed on the network.
A Doubles that meet the HPFV specifications, which include strict safety and emissions requirements, will have improved access on these routes.
In addition, the Government is also issuing six new A Double Tanker networks to help streamline the transportation of milk and other liquids across the state.
These routes have been developed with industry and tailored specifically to A Double tankers, which have different specifications and requirements to other A Doubles on the network.
The routes would provide more simple, safe and connected journeys for the movement of key products such as milk, grain and livestock in regional Victoria.
The expansion of the HPFV network only includes roads in regional Victoria and any trucks coming into metropolitan Melbourne will need to abide by existing curfews.
Truck curfews are enforced in areas including Melbourne's inner west, to limit the number of heavy vehicles in busy residential areas.
