The air clearance can be estimated from the tide gauge at Gorleston,

when the gorleston  tide gauge reads zero, there is an estimated  13ft clearance under the bridges,so if you know the predicted tide gauge reading for a given day,you can work it out,

take today, the estimated gauge reading(to chart datum) is 0.38 metres=1.246 feet, so clearance would be

13-1.246=approx 11ft 8 inches,

here,s a link to the tide tables it,s based on
