Piercebridge Roman Bridge

The bridge carried Dere Street Roman road across the river.[1] Piercebridge Roman Fort guarded the bridge.[2]

The first bridge was built around 90 AD, but this replaced by a second bridge after it was washed away. The Tees has narrowed and changed its course over the centuries so the remains lie in a field around 90 metres (300 ft) south of the current course of the river, and about 450 metres (1,480 ft) east of Piercebridge.[3][4]

What remains of the bridge are massive masonry blocks that formed at least five piers.[5] The lower courses of one of the abutments still stand, partially complete, and it is possible to see the holes into which the wooden structure of the bridge would have fitted.[6] All of the timber has disappeared in the nearly 16 centuries since the end of the Roman occupation.[7] The remains were discovered in 1972 during gravel quarrying.[3] The stone blocks are up to 1.5 metres (4 ft 11 in) long and the total bridge structure was 123 metres (404 ft) long.[8][9] Artifacts from the excavation of the bridge and fort are held in the Bowes Museum.[1][10]

Whilst the majority opinion among archaeologists is that the structure is a bridge, an alternative interpretation has been proposed by amateur archaeologist Raymond Selkirk, who contends that the structure is a navigation dam with an overspill channel. From this, and other evidence he argues that the Romans made far greater use of river transport than is generally recognised. His views are set out in his books The Piercebridge Formula (1983), On the Trail of the Legions (1995) and Chester-le-Street & Its Place in History (2000).[11][12]
