it was a motorway flyover wasnt it ?
No it was in the town of Falmouth which is situated between some very very steep hills.
I add the photo to illustrate the steepness of some of the areas around Falmouth the pic is of Jacobs Ladder. (theyre a bugger to ascend with shopping bags though there is a pub at the top. lol)
I heard that the guy died but then it could be an Urban Myth ?
