Experts have been called in to investigate what is believed to be the remains of an ancient wooden road.

A trio of Birmingham University archaeologists were contacted after contractors working in Suffolk unearthed a number of vertical timbers thought to have once supported an ancient causeway.

Experts said excavations at the site of a multi-million pound flood alleviation project for Broadland had revealed the remains of a structure which ran for more than half-a-mile, from the edge of Beccles Town marshes, across a swamp to a spot on the River Waveney.

The causeway is thought to date from the Bronze Age and remained in use into Roman times until the fourth century.
