See (S5) and NHER 4235.
E. Rose (NLA) 29 March 1996.

Excavation revealed all elements of the Fen Causeway in section.
A layer of rammed briquetage was submerged by water (lain silts and clays). Natural material and more briquetage was heaped upon this to form a domed bank nearly 1 metre high. Rammed orange gravel was used for the first metalled roadway, possibly by the late 1st century.
A canal to the north parallel to the road. The canal bank produced late 1st/early 2nd century pottery. The canal functional into the 3rd century.
2nd century pottery recovered from dumped briquetage waste indicative that the production of salt was taking place in the vicinity.

25 July 1996. NLA air photography.
Cropmarks of field system, enclosures and turburies still visble.
Also present is a square ditched enclosure to the northwest of the site around [6]. This enclosure appears to be on a slightly different alignment to the Roman enclosures and fields. Located within this square enclosure is a ring ditch. This may be Bronze Age. It is not clear whether the ring ditch and enclosure are directly related.
