I always get stuck at this bridge when coming off the ferry at Holyhead as it's 2 lanes each way except for the bridge which is single lane in both directions.
It must drive the locals nuts.
The lanes on the bridge look quite wide, could they fit 2 lanes eastbound and one lane westbound as westbound never seems to be a problem.
They'd need to reduce the speed limit to 30 but it would keep things moving.
