Further abuse towards staff during repairs on a busy bridge could lead to its closure, drivers have been warned.
Workers were withdrawn over safety concerns earlier this week after a confrontation between a member of the public and staff monitoring vehicles using the 200-year-old Menai Bridge, one of two linking Anglesey to the mainland.
A reduced weight limit was put in place after the hangers – which lift the suspension chains and the road – were found to need repairs. Other work is expected to take until 2027 to complete, prompting local frustration.
Highway officials said abuse had become a “common feature” and harassment would now be referred to North Wales Police.
“The latest incident placed the welfare and safety of operatives at risk so the decision was taken to pause operations,” said UK Highways A55 Ltd.
“There have been several incidents where vehicles have ignored the directions of operatives and crossed the bridge regardless.
“An overweight vehicle crossing the Menai Suspension Bridge requires a precautionary check to assess any potential damage.”
Lorries over 7.5 tonnes have had to take a detour since the upgrade work was identified, with checks undertaken and traffic lights installed on the bridge.
One vehicle which crossed on Monday was found to weigh 15 tonnes although the driver said it was under 7 tonnes, Traffic Wales said in a post on X, external.
