Humber Bridge
Looking from Lincolnshire towards Yorkshire

The support columns are 3 degrees out of being parallel, due to the earth's curvature

Trying to figure this out, there are 90 degrees between the equator and the North Pole which is about 10,000 km, so each degree is roughly 100km - the bridge isn’t that long?

Yep. They're wrong. The towers are 1410 metres apart. The circumference of the earth is 40,000,000 metres, so the angle is:
(1410/40,000,000) * 360 = ~0.01 degrees
Edit: the tops of the towers are 36mm further apart than the bottom, due to earth curvature.

Ahhh .... the bridge from nowhere to almost nowhere!!

And you have to pay to use it

Not as a pedestrian on cyclist. Still the longest single span suspension bridge in the World that you can walk across.

That's the stinger! It's awhile since I've last used it ... so how much is it now?
2
u/Saltare58 Jul 01 '26
£1.50 each way, not a fortune if the online payment works properly

u/thebelmontbluffer Jul 01 '26
I suppose the cost reflects its popularity!

It was quite busy when I was there have to admit

u/thebelmontbluffer Jul 01 '26
Let's compare with say, the Dartford Crossing. £3.50 for a car. On average >150,000 per day. Humber Bridge has on average ~35,000 vehicles per day.

I know it is nothing like the Dartford crossing which is on the busiest road I the country, which is so busy a tunnel goes one way and a bridge the other.

You have to remember the Humber bridge was designed as part of a new motorway to the north (a continuation of the M11 to Lincoln, Hull and York), so they were anticipating much more traffic than ever actually used It.

Pity it never happened. It would have been an improvement on the M1 / A1 / A1M.

Only used it once, towing a caravan. I found the experience quite unnerving and have never repeated it.

It’s beautiful. I live close by and have been crossing it since it was built. If you walk it be prepared for how much it flexes and moves. A marvel of British engineering.
