Excavations along the M25

"A total of 29 sites were investigated along a route that transected the districts of Epping Forest, Brentwood and Thurrock in Essex and the London Borough of Havering, passing through the ancient parishes of Epping, Theydon, Garnon, Theydon Mount, Stapleford Tawney, Navestock, South Weald, Great Warley, Upminster, Cranham, South Ockendon and Aveley. Principal sites were identified at Hobbs Hole (Junction 29) and Passingford Bridge Widening and Flood Alleviation Area, although significant archaeological remains were also uncovered at Upminster Bund, Codham Hall Bund and Pond 1812. In addition, archaeological features of interest, largely charcoal-rich pits and isolated prehistoric pits, were recorded at ponds 1605, 1609, 1615, 1683, 1791, 1824 and 1835"--Page 1.
