The Weymouth Relief Road crosses an area of intricately varied geology
and one of the richest and most important cultural landscapes in
England, which preserves a wealth of archaeological and historical
remains. Extensive fieldwork in advance of construction of the Weymouth
Relief Road yielded evidence of Neolithic, Bronze Age and Iron Age
settlement and funerary activity, along with vestiges of Roman
occupation.
The main sites were located at Ridgeway Hill, located on the edge of
South Dorset Ridgeway, at the northern end of the scheme and at
Southdown Ridge close to the southern end. At Ridgeway Hill a sequence
of Neoltihic pits was investigated, along with several groups of early
Bronze Age inhumation and cremation burials in pits and cists. The
burials were probably originally associated with barrows that belonged
to the Ridgeway Hill group, one of the densest concentrations of Bronze
Age round barrows in Britain. At Southdown Ridge a settlement that
spanned the late Bronze Age/early Iron Age to the late Iron Age was
discovered lying adjacent to a cross-ridge dyke and prehistoric field
enclosures. The inhabitants engaged in shale-working activity as well as
agriculture until the settlement was abandoned and converted to a
cemetery in which the dead were buried in the distinctive south Dorset
tradition, accompanied by grave goods, and later in the Roman tradition
of coffined burial.
