Several kilometres of fencing will be installed along Picton Road to stop local koalas from becoming roadkill.
It is part of the NSW Government’s Koala Strategy announced earlier this week.
Similar fences could be installed along Appin Road between Campbelltown and Appin.
An Office of Environment and Heritage spokeswoman said the Picton Road fencing would cost around $1 million.
“Approximately 5.5 kilometres of new fencing will be installed on both side of Picton Road from south of Wilton to the power transmission line easement,” the spokeswoman said.
“The proposed fencing will help secure koala passage along Allens Creek and Cascade Creek, two of the most important koala corridors in the region.”
A spokesman for Roads and Maritime Services (RMS) suggested koala protection measures would form part of a planned upgrade of the northern end of Appin Road.
“As part of the proposed upgrade of Appin Road between Rosemeadow and Appin, RMS is investigating koala protection measures including the installation of barrier fences to guide koalas away from Appin Road, aiming to reduce the number of koalas and other fauna being struck by vehicles,” the spokesman said.
“Other measures being investigated include avoiding vegetation clearing where possible, particularly koala habitat along Appin Road, and engaging an ecologist to carry out targeted inspections of work areas before and during construction.”
