A46 Newark Bypass finds: archaeology impacts on design, earthworks and programme

30 Second Briefing
Pre-construction investigations for National Highways’ A46 Newark Bypass upgrade have uncovered seven human burials, a Roman well and two probable Anglo-Saxon timber houses on the proposed alignment. The finds, made during archaeological trenching and strip-map-and-record works, confirm multi-period occupation immediately adjacent to the existing dual carriageway. Designers and contractors will now need to factor in preservation in situ or controlled excavation, with potential programme and earthworks phasing impacts on this strategic A-road improvement.
Technical Brief
- Human remains trigger strict handling, recording and reburial protocols under UK burial and heritage legislation.
- Presence of a Roman well implies deep, localised excavations intersecting groundwater, affecting dewatering and temporary works design.
- Anglo-Saxon timber structures indicate shallow, fragile features vulnerable to standard topsoil strip and bulk earthworks.
- Archaeological trenching and strip–map–record methods require phased access, influencing traffic management and construction sequencing.
- Safety management must integrate archaeologists into site induction, exclusion zones, plant–people interface controls and permit-to-dig systems.
Our Take
Discoveries such as the Roman well and probable Anglo-Saxon houses on the A46 Newark Bypass typically trigger tighter method statements and exclusion zones, which can have knock-on effects on temporary works design and traffic management plans even when the main scheme geometry is unchanged.
New Civil Engineer’s broader coverage, including its webinar on digital handover, suggests that schemes like the A46 Newark Bypass are increasingly expected to integrate archaeological records into BIM and asset information models, so early coordination between archaeologists and information managers is likely to become standard practice.
