This is a road bridge over a branch of the River Thames, having relatively shallow cast iron beams, with brick jack arches in between. The load-carrying capacity was inadequate for modern traffic, and its strength needed to be markedly increased. This was achieved in 1999 using an ingenious and completely unobtrusive solution using pre-stressed carbon fibre plates bonded to the underside of the beams. Clamping plates for the carbon fibre reinforcement can be seen in photo 2.
