The bridge was constructed in the 14th or 15th century and comprises six arches of various heights and widths, the middle three of which span the river.
The bridge is a Grade I listed building and a scheduled ancient monument.
[1][2] Teston Bridge is built of coursed rag-stone with ashlar capping stones to the parapets.
The bridge is narrow, only wide enough to permit traffic to pass in one direction at a time and the parapets feature pedestrian refuges continued up from the cutwaters on each side.
[1] It carries the B2163 road, which is crossed on the level by the Medway Valley Line just west of the bridge.
