The bypass would take traffic away from Bontnewydd
Plans showing four possible routes for a bypass at Bontnewydd in Gwynedd have gone on public display.
But already there are differences of opinion with a dispute about the route between Bontnewydd and the coast.
A local councillor said the bypass should go the other side of the village and make use of existing roads.
The routes also bypass Caernarfon, and the town's mayor said any road should pass by the Cibyn Industrial estate to improve the local economy.
Hywel Roberts added that taking traffic straight off the A55 to the industrial estate was essential.
"We need to develop the industrial estate to improve employment opportunities in the area," he said.
Councillor Chris Hughes, the Gwynedd councillor for Bontnewydd, said there was a lot of traffic travelling through the village, all day, not just at peak times.
"The consensus in the area though is that the route would be better off above the village," he said.
"We were told in a presentation by the assembly (government) last night that if people wanted then it is possible to look at another route."
He added that he thought use should be made of the road from Bontnewydd to Caeathro to save on having to buy land, and to make use of a road which was already an "unofficial" bypass for Caernarfon.
Ifan Jones from Bontnewydd said he had lived in the village for 30 years and a bypass was badly needed.
Even people who do not live in the area agreed.
Said Rhys Jones, who sometimes has to travel through Bontnewydd with his work, said: "I've noticed how bad it is whenever I travel south of Caernarfon.
"I wouldn't like to have to drive to work from the direction of Porthmadog every day, as it's busy all the time at Bontnewydd," he added.
The Welsh Assembly Government is asking local residents to comment on one of four possible bypass routes to help cut down on queues in the village.
The study will last 12 weeks and include public exhibitions at Bontnewydd and Caernarfon.
Projected costs for the new roads range from £40m to £86m depending on the route chosen.
The public exhibitions will be held at the Celtic Royal Hotel in Caernarfon on Tuesday and Wednesday 9 and 10 March from 1000-2000 GMT, and Thursday 11 March from 1000-1400 GMT, then on 16 March at Canolfan Bontnewydd, The Old School, Bontnewydd from 1000 to 2000 GMT.
