HORSHAM Rural City Council will request detailed information from VicRoads about the final route for the Horsham bypass.
Cr Mark Radford suggested on Monday night that council ask VicRoads to provide clean and complete information to the community about how a final Western Highway bypass route is decided.
Council made a submission to VicRoads about the planned bypass last month and criticised the authority for failing to explain its decisions on the location of the bypass.
VicRoads shortlisted bypass routes 11, B2 and a combination of both - which bypass Horsham to the north-east - in December.
Options 5A and 12 -which bypass the city to the south-west - were eliminated after detailed investigations.
In its submission, council asked VicRoads to consider a fourth option, another combination of routes 11 and B2.
Council met with VicRoads regional director Ewen Nevett late last month.
Cr Radford said one of council's roles was to minimise the impact of the bypass and understand how VicRoads made its decisions.
"We are not getting a lot of information as to how VicRoads are coming to their decisions," he said.
Cr Robin Barber said he left council's meeting with Mr Nevett disappointed.
"He seemed pretty adamant that what was proposed was going to happen," he said.
Cr Tony Phelan also expressed his concerns about the project.
"I support a bypass around Horsham and I recognise that wherever it goes it will affect someone in some way, but I am concerned about the rights of those affected," he said.
"There are justifiable social, economic and environmental concerns."
Cr Phelan said it was a basic requirement that people saw why bypass routes had been selected and rejected.
"At the moment, there is no basis for response," he said.
Cr Pam Clarke said she worried about how the bypass would be built in a flood plain and its impact on the amenities of the rural settings in the Riverside and River Heights areas.
