Tomos Mather who lives locally said the closure would be hard on businesses in Menai Bridge.
“Work has been going on for three years. If it was so severe they had to close it so quickly you’d have thought they’d have found that over the past three years,” he said.
Huw Roberts who also lives locally, said he had hoped by now “they would have done a better job”, adding “it just seems like a long time”.
“The main problem is getting to and from Bangor – we now have to do a four mile detour over the Britannia Bridge,” he said.
“That bridge, when the ships come into Holyhead… the traffic is horrible.
“It will take half an hour, three quarters to get to Bangor instead of ten minutes.”
