Mr Manning said farm owner David Pearce had been "very generous" in again allowing access across his farm. "Obviously, developing a new road would provide a permanent solution."
But he said the council's immediate focus was getting Limeworks bridge re-opened and that was on track to happen in three weeks.
He said Mr Pearce had even offered to gift the land needed for the alternative road through his property, but there was "a lot to be done" before that was resolved. "There are other landowners involved so we'd need to have discussions with them as well. Another key in all of this is the involvement of the NZ Transport Agency," Mr Manning said.
NZTA manages Government funding for the state roading network as well as partial funding for local authority road works.
He said the upside of a new route meant there would be no need for a bridge across the Waitotara River to service the meat plant and the settlement at Waiinu Beach. About 40 people lived there permanently with numbers swelling during weekends and holiday periods when bach owners turned up.
Wanganui company Emmetts Civil Construction was at the bridge carrying out repairs.
