Safety upgrades to the Monaro Hwy including new guardrail, shoulder widening and audio-tactile line marking will be carried out from this week at Rock Flat.
A Roads and Maritime Services spokesperson said the NSW government provided $331,980 for the safety improvement work under the Safer Roads program.
"Audio-tactile line marking, where small bumps are placed on the edge of the road or the centre line, is a highly effective road safety treatment especially at night and in wet-weather conditions,"the spokesperson said.
Work will be carried out from Monday, May 13, on weekdays between 7am and 6pm and Saturdays from 8am to 1pm, and is expected to be completed by June 7, weather permitting.
Changed traffic conditions will be in place during work hours for the safety of workers and motorists, including a reduced speed limit of 40 km/h, single lane closures and stop/slow traffic control.
