THE plan to use a suburban Cherrybrook street as a feeder route for North West Rail Link commuters could be reviewed.
Castle Hill MP Dominic Perrottet has written to Transport Minister Gladys Berejiklian to ask for a review of the use of Robert Road, Cherrybrook as a thoroughfare for buses and cars to the rail link's Cherrybrook station.
"The Robert Road area is a quiet neighbourhood and I believe the major access point to the station should be via roads which have greater capacity to deal with increased volumes of traffic," Mr Perrottet's letter, which was distributed to residents, said.
He asked for studies to assess alternative routes such as County Drive, which Hornsby Council and a local resident action group back as the preferred option.
The council is considering reopening lanes on County Drive.
"Providing bus access from Castle Hill Road via County Drive could potentially have a lesser impact on Cherrybrook residents and should seriously be considered as well as any other proposals that may mitigate the impacts on the local community," the letter said.
It is estimated a bus will travel up Robert Road every three minutes in peak periods.
Mr Perrottet said he had not yet received a response from the minister's office.
