Why would you build this?

Mrs. Woody and me went for a drive out today Nothing planned and as I said to Mrs. W when asked our destination I said its a bit like the Toyah song from the 80s, Its a Mystery (see Toyah here)! Eventually we ended up on the back roads of a village called Burton Le Coggles in Lincolnshire. Not a great deal there apart from a pub and Jades farm shop which has a great selection of traditionally vegetable and  meat products as well as a range of specialist foods and gifts. You don't find many places with such a nice looking set of fruit and veg!

Apart from highlighting that I will be enjoying some of Jades burgers next week lets move back to the appropriately named Back Lane.

Nothing unusual about the lane but looking down what is a dirt track there is a massive bridge carrying the East Coast Main Line over it. 

Coming in closer the scale and no doubt the high cost of this bridge over nothing more than a dirt track become clearer. It has to be nearly 40 feet high and the arches are wide enough to build a wide two lane road through them with ease.

Why would you build such a costly structure over a dirt track when a simple culvert type construction would have accommodated the local farm needs? I have tried to find out if there is some historic significance to the track which might explain the bridge but to no avail, so its a mystery! However you have to admit that that whole scene in the picture would make a great model if you had the space!
