Cattle and sheep producer Scott Kensit's property 'Hollywood' is blocked by two bridges along a B-double route between Boorowa and Crookwell.

Along the Boorowa Road over Wheeo and Old Man Gunyah creeks load limits have been reduced to 7 tonne (single axle), 8 tonne (tandem axle) and 11 tonne (tri axle).

Mr Kensit regularly transports stock along the route to feedlots and sale yards.

"All my steers go to feedlots, a lot go out through Boorowa. If I go to Carcoar they would normally go along that route," he said.

"Last year I had three B-doubles come in with fodder and three semis' worth of grain, as well as truckloads of sheep and loads of cattle.

"I'll just have to wear it, but it limits my markets I can send stock to."

Daniel Osborne, NSW Rural Fire Services Southern Tablelands Zone operational officer, says his crews regularly drive vehicles with a weight range from 3.5 to 13.7 tonnes.

"We are working with the council and other stakeholders to implement suitable arrangements to ensure our service delivery is maintained," Mr Osborne said.

Upper Lachlan Shire Council is looking into the installation of temporary measures at the concrete bridges.

"The council apologises to the community for any inconvenience caused but public safety must be our number one priority," acting general manager Andrew Croke said.
