By Transport for NSW

Work is continuing along the Monaro Highway as part of the $20 million program to improve safety and efficiency of the important link between the ACT and the Victorian border. 

A Transport for NSW spokesperson and the second project of the Monaro Highway upgrades is set to get underway next week and consists of installing a Mass Action Roadside Safety Barrier from Rock Flat to Nimmitabel.

"There were 15 crashes recorded on this stretch of the Monaro Highway from July 2017 to July 2022, resulting in one fatality and three serious injuries," the spokesperson said.

"To reduce the risk and severity of run-off-road crashes, more than six kilometres of new safety barriers will be installed at various locations along this stretch of the highway.

"Additionally, motorcycle underruns will be added to sections of existing safety barriers to provide further protection to motorcyclists."

The spokesperson said that as a key connection to the NSW ski fields and Kosciuszko Nation Park, the Monaro Highway generates significant seasonal traffic flows during the June to October ski season. 

"We are committed to providing safe and efficient journeys for locals, the tourist industry and all who use this 205-kilometre stretch of road.

"The first project as part of the Monaro Highway safety upgrades has seen more than 50 kilometres of widened centrelines and rumble strips being installed between Cooma and the ACT border.

"We are pleased to see progress steaming ahead on these critical upgrades with the first project complete and the second about to start."

Work will be carried out from Rock Flat to Nimmitabel from 7am to 5pm on weekdays from Monday 10 July to Friday 1 September, weather permitting.

Single lane closures, traffic control and a reduced speed limit of 60 km/h will be in place during work.

Transport for NSW thanks the community for its patience while work is carried out.
