  1. Has anyone considered the effect of the increase in average vehicle weight on bridges?

    Many years ago I read an engineering report on the first Severn Bridge, in which some of the problems that bridge had in its early years were said to be due to all the toll booths being at the English end. This meant that traffic queuing to pay the toll, hence the vehicles were closer together than the flowing traffic on the other carriageway, was on the upstream side of the bridge. This caused the bridge deck to be slightly rotated, so the underside was exposed to the prevailing wind which in turn caused fretting of some elements of the suspension system leading to some premature component failures.

    If the increased density of queuing traffic compared to flowing traffic can cause a problem then surely the near-doubling of average vehicle weight will also be significant.

    Rich - just make sure all the bolts/nuts are properly tight

    Can I emphasise "properly tight" - doesn't mean as tight as you can get them. Overtightening can distort the mating faces and cause leaks.

  3. I was all fired up for the first local show of the year, the A47 autojumble, just checked the TR over, then saw that the show/autojumble is cancelled because the field is too muddy. :(
