Moulton Packhorse Bridge

A pretty four-arched late medieval bridge, spanning the River Kennett on the old route from Cambridge to Bury St Edmunds.

The bridge is built of flint and stone rubble, with plain parapets, and the edges of the arches are made of brick. Pointed arch shapes like these were constructed using wooden formers to support and shape them, and were not used after the 15th century. 

A concrete platform has been laid down alongside the bridge over the stream, at the level of the base of the piers, to allow cars to cross. The concrete extends under the arches, giving an unusual opportunity to look at the underside of the bridge.

The river has shrunk in size since the bridge was built in the 15th century. While a single arch would have been suitable to span a narrow stream, if used over a wider stretch this design would have created an inconveniently steep slope at both sides. At Moulton a series of smaller arches was therefore used to carry the road on a more manageable slope
