Former mayors Fred Longmire and Paul Miegel and Cr Gail Law also took aim at a flyer backing the green route which was distributed during the recent survey period which revealed 70 per cent of residents who completed the survey were in favour of the green route.

"I didn't support the intrusion of the democratic method of the survey," Cr Longmire said.

"The leaflet distributed by the green route advocates promotes at least four misinformation criteria.

"Along with the Victorian and NSW state governments and the silent majority of residents of Mulwala, I still support the grey route."

Cr Longmire said the green route flyer, which he tabled during the debate, falsely showed a future bypass along the railway line and wrongly raised hopes the existing bridge would be retained.

Green route action group spokesman John Lawless said the flyer material had been sourced from numerous bridge studies.

"It is just sour grapes from people who can't stand to lose," he said.

"Hopefully we can get together with VicRoads now and get this sorted out pretty quick.

"Then we need the federal government to step up and put the money up."

But, VicRoads North-Eastern regional manager Steve Bowmaker said there had been no change to its preference for the grey route despite the latest survey.

"We're continuing to work closely with our NSW counterparts on planning for a new Yarrawonga-Mulwala bridge," he said.

"While that planning continues, we are focused on progressing the associated Murray Valley Highway connection to relieve congestion and safety issues associated with heavy vehicles using Belmore Street through the Yarrawonga CBD."

Cr Bronwyn Thomas moved the council back the green route with deputy mayor Shaun Whitechurch seconding the motion, which was also supported by mayor Pat Bourke, Cr Andrew Kennedy, Cr Norm Wales and Cr David Longley.

Cr Wales previously supported the grey route as a former Corowa Shire councillor, but said the survey results had swayed his view.

Cr Law said the state government road agencies were still supporting the grey route and there was no chance the existing bridge would be retained.

"I feel this ongoing argument by the Moira Shire and green route advocates is only leading to the bridge being further and further away," she said.

"We are just holding things up, the sooner we agree with (Transport NSW and VicRoads) and get on with it the sooner the bridge is built."

Cr Kennedy said his biggest concern was the disruption the two communities would encounter during the construction phase which could still be a decade away.

Cr Miegel said the grey route served the dual purpose of trucks being able to avoid Belmore Street and ease of access to the Yarrawonga main street for local traffic.
