What is it with Putney Bridge?

A few weeks ago I highlighted the appalling state of Putney Bridge; in particular the bus lane, which had simply disintegrated. Wandsworth Council - who are responsible for Putney Bridge - got onto that one a good deal faster than they've dealt with some of the other potholes around the constituency - and the bridge was resurfaced.

But whether they used the wrong sort of tarmac, or there's some underlying erosion within the bridge, or their contractors aren't up to the job, there are already potholes in the new road surface, exacerbated by today's heavy rainfall.

Yes, a bus lane carries heavier vehicles than the rest of the bridge generally - but equally it is a far less used lane. There is no reasonable reason why newly-laid tarmac should last just a couple of months before needing to be repaired.
