The only links Gatehampton has with transport.London is that the
Thames is flowing towards London and the railway is running away from
Paddington! But that is my excuse for mentioning this lovely viaduct
by Brunell which was built at two diffrent times, using different
brickwork techniques, the two being attached to each other their full
length.

The Grosvenor bridges crossing the Thames outside Victoria were built
similarly, one track at a time, so that the old structure could be
replaced without having to close Victoria station.


The current London Bridge was built as four bridges: the outer spans were
built first, either side of the old bridge, and the traffic was transferred
onto them. Then the old bridge was dismantled and the inner spans built to
fill the gap.
