Ms McKay's call came in the wake of Dubbo MP Dugald Saunders announcing the state government would provide Dubbo Regional Council with a special grant of $100,000 to help fund investigations into a bridge for the southern part of the city.

"The new member is only new to his job, so we can't be too harsh on him, but he has to understand his job is to stand up for his community and not toe the government line," she said.

"He seems like a decent person, but he is a backbencher, and he seems to have no sway with the minister whatsoever which is why he seems to be defending something that he knows the community has a problem with."

Mr Saunders has said he does not believe there was significant opposition to the River Street bridge proposal.

He also believes the $100,00 allocation to the council shows he is listening to the electorate.

"I am supportive of calls for a south bridge, and this special grant will help council to fund a study into the best corridor for such a bridge," he said.

The Dubbo MP claims those that are against the bridge are in the minority and they don't represent the majority of Dubbo voters.

However, Ms McKay believes "it is quite obvious" there is a significant concern in Dubbo that proper process has not been followed.

"The money should be quarantined for Dubbo and a review done on the bridge placement, and that is an entirely appropriate thing to do because if it is a vocal minority as Mr Saunders has stated it will give those people assurance that proper process has occurred.

"Why can't he agree to stop the work and have it reviewed in a really transparent way with all the evidence put on the table, so the community gets a proper say?" Ms McKay said.
