Bridge Deflector Piers.

Bridge Deflector Piers.
There was a time during the early years of the iron bridge being built that there was quite a lot of barge traffic on the river. Most of this traffic was Thames Conservancy barges, which were loaded with gravel from the riverside pits at Marlow and for use further down stream in maintaining the riverbank from erosion.

It was quickly found out that during periods of a fast flowing stream that the barge helmsman would lose way as the tug slowed to make the turn into the lock cut. So three deflecting wooden piers were erected to prevent these barges from colliding with the bridge supports. Although the barge traffic has but all ended, the wooden piers on the upstream side of the bridge still remain.
