Bridge joints
 

I don't know the correct terminology, but I'm talking about the 2 rubber
strips across the entire road width which you get on either side of a road
bridge.

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?

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

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.

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

Thanks.
