Although there are 23 archaeological sites recorded within the study area, none is of national significance or protected by statute. They are all, at most, of local importance. Archaeological sites are thought to exist below the former ballast hill north of Tyne Street in Jarrow and the former Howdon shipbuilding and ship repair yard. The Howdon Pans Shipbuilding Yard may be considered of regional importance. However, there is no national assessment of harbours or shipbuilding and therefore no similar comparative information is available.

Due to the scale and depth of excavation required to construct the proposed crossing, it would not be possible to preserve archaeological remains in situ within the tunnel corridor. There is no evidence, however, that the construction works would affect any remains of sufficient importance to warrant such preservation. In those areas where the presence of buried archaeological remains are suspected, it is considered that the impact of the scheme could be adequately reduced through a staged programme of archaeological investigation undertaken in advance of and during the construction works.

The construction method and programme should reflect the outcome of the initial investigations and be designed so as to enable an appropriate level of archaeological investigative excavation and recording to take place. In all instances where ground investigation is undertaken, a written scheme of works detailing its scope would be agreed in advance with the County Archaeologist. All archaeological work would be carried out in accordance with guidelines provided by English Heritage.
