COUNCILLOR Elise Chapman has accused the City of Greater Bendigo of turning its back on residents.
Councillors last week voted against a two-lane service road on the eastern side of the Calder Highway in Marong, despite residents' safety concerns.
VicRoads - the governing authority for the service road - says one-way access is the safest option.
Councillors agreed to lobby VicRoads and the state government in a push for two-way access in February.
But councillors have now voted to deny two-way access after the Transport Minister deemed the one-way design adequate.
Cr Chapman has dubbed the decision "pathetic".
She said the council had not tried hard enough to lobby the governing authority.
"Ninety per cent of the town is against this and we are snubbing our nose at them," she said.
"We voted to allow two-way access this year and not one thing has changed since.
"At least five councillors were against this so where's that courage gone?
"The only thing council has done is sent a letter to the minister.
"So are we just going to be steamrolled?
City of Greater Bendigo chief executive Craig Niemann said the city's lobbying efforts had been adequate.
"We have written an appropriate letter to the minister and have been in correspondence," he said.
"And after all of that, their position hasn't changed.
"They won't allow two way access."
Cr Rod Campbell said safety had "won out" on this occasion.
"With a background in civil engineering, and also knowing the town intimately, I know this will help avoid head-on collisions on the road," he said.
"I know residents will be disappointed but this will ensure their safety and that is our priority."
Cr Barry Lyons reluctantly supported the one-way road.
"This has been impacting on Marong itself so unfortunately we are going to have to go along with this," he said.
"We just can't drop the ball on this one."
The city will investigate other options for a truck stop in the area, to reduce congestion.
