But how did you FIRST find out you could fit under it?
I do sort of agree, at least make the height restriction right with a % tolerance. Stops people chanceing it
I had been told by my dad (also a truck driver and now passed away), and other drivers that the A36/14ft bridge at Wilton was good for a container truck with a standard height 20/40ft container but not passable with the higher high cube container. So when I had a high cube on I avoided the bridge by using less suitable roads (unsuitable but the only alternative), I carried on under the bridge with standard height boxes.....
It was while using the route with standard boxes i noticed I was passing other trucks who DID have high cube boxes on, I quickly come to the conclusion that these trucks HAD to be going under the bridge as there was nowhere else they could be coming from/going to, having kept an eye on who/what I was passing I worked out I was passing makes/models of wagons/trailers exactly the same as mine. So then it was a waiting game of actually physically watching one pass under, when I did I was quite surprised what I seen, that being a quite distinct gap between bridge and container, with the average slider trailer/high cube combo being 14ft 9 given the gap I seen I would say the bridge is more 15ft 1-15ft 3, having witnessed what I had I took a high cube under, very slow the first time, sure enough, as per all the other trucks before me, it fitted and I've been going that route ever since, however now I just slow to speed that doesn't inconvenience others but keeps the truck stable.
So going back to the poster above, why is that road marked up as 14ft, when the bridge is at the very least 15ft? After all, trucks don't jump, and they don't bounce that much.
