Work on Barton Highway Duplication begins

The project aims to ease congestion on the arterial road, which connects the ACT to NSW.

This comes after the federal government invested a $100 million boost after the initial $50 million investment from NSW and federal government.

Meanwhile, the NSW state government has allocated $24 million to the highway duplication in its 2020-21 budget.

"The Barton Highway is a crucial part of the NSW and ACT transport network, connecting communities to essential services, employment, healthcare, education opportunities and integral freight movement," Deputy Prime Minister Michael McCormack said.

NSW Minister for Regional Transport and Roads Paul Toole said he expected the first stage of the development to create 80 jobs.

"Early works will involve site establishment and utility relocation work, with major works to build what will ultimately be new northbound lanes from the ACT border to Kaveneys Road to start early in 2021," Mr Toole said.

Senator for NSW Jim Molan said the stretch of road in Hall was prioritised due to high traffic volumes and crash rates in other sections.

"The upgrade will also meet growing transport demands, ease congestion approaching Canberra and improve safety for through, local and tourist traffic along the corridor," Mr Molan said.

The Eden-Monaro byelection also put a spotlight on the Barton Highway.

Member for Canberra Alicia Payne brought up a concerning trend in Question Time earlier this year, asking Prime Minister Scott Morrison what the solution was for regional women forced to give birth on the highway while on their way to hospitals in Canberra.

"Well, I'm pleased to let the member know that's why we have committed $150 million to upgrade the Barton Highway," Prime Minister Scott Morrison said in June.

The Prime Minister's comments plugging the upgrade sparked outcry at the time, as the town of Yass has not had specialist maternity services since 2004.

The duplication is expected to have a 100km/h speed limit.

The first stage of the duplication is expected to be completed by late 2021.
