Expansion Joints (buffer space to take up expasion of beams on hot
days)

I learnt something! I thought they were to stop bridges collapsing in an
earthquake.

I notice that one of the bridge joints in Primrose Street has been
covered by the new bricked road surface... Is this a cock up, or are
bridge joints not really necessary?

If they are just short beams, I'd expect that the 'bricks'would adapt
to fill the space, and voids when cold would not be noticed. (I
wonder what sort of joint is beneath the bricks?)
If this were a 500m beam, I don't think it would be a good solution.

Thanks.
