Not splitting hairs but 15 foot is 4.57m 4.6m is 15ft 1.1 inches. Resurfaced road maybe and bit to high. They made it halfway poor lad. Think I’d of taking it a bit easier being at that height though. Wise after the event I know but have to feel for them
When a bridge has both imperial and metric markings, then it’s not a conversion between the 2, each are measured then rounded down to their own criteria, so you’ll get bridges marked with the same Imperial heights and different metric and vice versa
