A gas tanker has overturned on the outskirts of Rhoscolyn.
The road between Four Mile Bridge and the village was closed for around seven hours following the lorry crash at around 10.55am on Wednesday morning (6th November).
The driver was assessed at the scene by paramedics but escaped injury.
North Wales Fire and Rescue Service asked anyone living or working near the scene of the crash to close their windows and doors while recovery work took place.
They later reported there was no risk to the public or the environment.
During the road closure, a North Wales Police spokesperson urged the public to stay away from the area for their safety and asked drivers to use alternative routes.
