This is a stunning sight and I am afraid I cannot lay my hand on a photo at the moment. It makes it well worth your while to travel over to the East for a break, perhaps in lovely Beverley, not too far from the north side of the bridge, as you head northward.
Obviously I have not measured it and the statistics here come from the bridge website: http://www.humberbridge.co.uk/
It is a suspension bridge with a main span 1,410 metres long and side spans of 280 meters and 530 meters respectively, North and South. There is 30 meters clearance over high water and a tower height of 155.5 meters.
Prior to the building of the bridge, traffic between, for instance, Hull and Grimsby had to go miles inland to cross the river at Goole. The building of the Humber Bridge seemed to make sense of the County of Humberside, created in the 1970s by abolishing the old East Riding of Yorkshire and putting it and part of Lincolnshire into the new county. The high tolls for using the bridge may have contributed to the dislike of Humberside on the South Bank though I guess it was more the feeling of having been taken over by the North which led to the campaign, eventually successful, for the South bank to revert to Lincolnshire.
The bridge has to be closed to high sided vehicles when there is a very strong wind as the Munber acts as a sort of wind tunnel.
There are fine viewing areas on both banks and, because of the width of the estuary, it can be seen from a considerable distance away.
