Representatives from the council, including the Mayor John Stafford, acting general manager, Andrew Croke and the director of infrastructure, Mursaleen Shah, fielded questions from the Bigga Progress Association as well as the audience.

Mr Shah has met with the Roads and Maritime Services and the Transport for NSW engineering team to determine a path forward.

Further information will be made available soon.

The council has identified bypasses either upstream or downstream at a majority of the 12 timber bridges, which had weight limits imposed in late July. However, they will need Department of Primary Industries' approval before works can begin.

A time frame was not yet available.

"We are going as fast as we can," Mr Shah said.

"In some areas it is easy to implement a bypass or side track."

Early recommendations to improve Old Man Gunyah bridge on the Boorowa Road may ease load limits.

Priority bridges will be identified based on a number of parameters; bus routes, traffic flow, alternate access routes and the number of affected properties.

Regulatory signs which are now displayed at the bridges are enforceable by law, with no exemptions.

"These load limits are largely related to the structural integrity. The bridges could collapse," Mr Shah said.

Most of the bridges that have loads limits imposed were constructed before World War Two, Cr Stafford said.

"This is clearly the biggest issue we've been confronted with," he said, reflecting on his three years in council.

However, the residents of Bigga and landlocked land managers face an uncertain future while they wait for alternative access.

Helen Faros, owner of the Bigga General Store said for the first time she'd have to put a sign up saying 'no fuel.'
