Wannon MP Dan Tehan told The Standard that an announcement for the stretch of road in the Wannon electorate was imminent in coming weeks.

"I have been working very hard and pushing the case for us to need to invest in the Princes Highway, and I am confident that we will hear some positive news over the next couple of weeks," Mr Tehan said.

"I have been in regular discussions with the Deputy Prime Minister and Minister for Infrastructure Michael McCormack, and I continue to bend his ear on the importance to continue to invest in roads in south-west Victoria."

It's understood the announcement could include the National Land Transport Network recognising the highway's importance, honouring projects Mr Tehan promised before last year's election, and the start of investments in key sections of the road.

Mr Tehan and Mr McCormack announced an initial $80 million for upgrades to the Princes Highway along with the Henty Highway, the Portland-Nelson Road and the Portland-Casterton Road last year.

Mr Tehan also announced $60 million for upgrades between Port Fairy and Warrnambool but the state government is yet to commence those works or agree to match the funds.

"Infrastructure is going to be a key driver in helping to us to drive jobs in the post-COVID environment," Mr Tehan said.
