Whanganui District councillors are frustrated at the wait for work to start on repairing the Anzac Pde slip near the City Bridge.
It's been more than two years since floodwaters washed out a large section of the bank near the Portal St intersection with State Highway 4 bringing down the walkway and part of the road.
At council's infrastructure and special projects committee on Tuesday councillor Rob Vinsen said most people assumed it was the district council's responsibility when in fact it was New Zealand Transport Agency controlled road.

Mr Vinsen was also concerned the slipping was putting the City Bridge abutment at risk.
"It's getting really close to it."
Council infrastructure manager Mark Hughes said there was no present danger to the bridge.
"We have had engineers assess it and we are okay at the moment. We are keen to get that work started but there is no immediate danger."
Mr Hughes said NZTA were ready to go but there had been issues getting resource consent from Horizons Regional Council for the right amount of time.
"We are not involved in it. It's out of our hands."
Mayor Hamish McDouall said council had done all it could and he was hopeful work would begin in October as he had been told.
"I think our media tub thumping has had some effect but if there's no yellow machine there in October I'll start getting annoyed," he said.
"All we can do is complain loudly and advocate."
Councillor Philippa Baker-Hogan said it was a "real inconvenience" and urged NZTA to start as soon as possible.
"We should pretty loudly say that we are unhappy about this."
Councillor Graeme Young believed the delay was a symptom of losing an NZTA office from the city.
"The loss of NZTA from here, I think, has had a significant impact."
Last month Transport Minister Simon Bridges' office said the riverbed was significantly different to what NZTA had found at other sites.
"The slip site has a high number of underground services, including water mains, which NZTA needs to work around."
