Traffic congestion on Picton Road will be eased with two new heavy vehicle rest area acceleration lanes.
Construction work is under way on the lanes, which will allow 3400 motorists and 410 B-doubles per day to re-enter Picton Road safely.
The federal and state funded project will cost more than $4.6 million.
Hume MP Angus Taylor said the federal government has committed $2.28 million to fund the project.
“Currently, the exits from both rest areas are give way-controlled T-intersections with a speed limit of 100 kilometres an hour on Picton Road near both rest areas,” he said.
“By building new acceleration lanes, heavy vehicles will have the time and space to merge with flowing traffic.
“It will improve safety for all road users while enhancing travel times and freight efficiency.”
Wollondilly MP Jai Rowell said the state government was kicking in $859,000 to complete additional safety improvements on Picton Road.
“These additional works will involve widening the road shoulders and installing a median safety barrier along Picton Road between the two rest areas,” Mr Rowell said.
Completion of the upgrades is expected by August 2018, weather permitting.
