A47 North Tuddenham to Easton Ground investigations and surveys A47 North Tuddenham to Easton improvement This leaflet is to update you on progress of the proposed A47 dualling between North Tuddenham and Easton. We will be carrying out further surveys and ground investigations to supplement our 2020 surveys and to give engineers a more detailed picture of soil type, depth and nature of rock types and groundwater levels. This work will be visible to those living and working in the area. The information gained will help us manage the design, in readiness for the start of works planned in 2022/23. What is happening and where? We’ll be using a variety of ground investigation techniques including boreholes, machine excavated trial pits and ground water sampling. We will require access to certain areas of land to enable this work to take place and will contact the appropriate land owners. During summer 2021, we will be investigating the area along where the proposed road changes will be made. 2 3 B1535 Ringland Road Norwich Western Link Hockering Wood proposed route Wood Lane Sandy Lane Easton - new bridge Proposed Norwich for walkers and Western Link cyclists A47 connection Taverham Road Proposed A47 North Hall Farm underpass Hockering Parish Tuddenham to Easton improvements (dualling) Existing bridge New bridge over Church Lane over the River Tud the River Tud Proposed North Tuddenham Heath Road Wood Lane Dereham Road Parish junction Proposed A47 North Hockering Hill Lane Tuddenham to Easton Bridge over Easton improvements (dualling) Mattishall Lane Lyng Road link road St Michael’s St Peter’s Church Church The Street St. Andrew’s Noise Proposed A47 North Church underpass fencing Trafc calming Tuddenham to Easton measures improvements (dualling) Noise Hall Road fencing Honingham St Andrew’s Bridge over link at Church Wood Lane junction Norwich Road Security Noise and visual Gate Noise and visual Proposed lay-bys screening banking Fox Lane screening banking junction Mattishall Lane Easton Marlingford Road A47 Trafc calming Low Road link road measures Honingham Parish Noise Roundabout fencing Mattishall Lane Berry’s Lane Proposed improvement Mattishall Road Proposed Fox Lane at Rotten Row junction Church Lane Norwich Road junction Bridge over link at Norwich Road junction East Tuddenham Parish Colton Road Honingham Parish Blind Lane Proposed A47 North Tuddenham to Grade I listed building Ancient woodland Flood area Easton improvements Low Road Grade II listed building Site of Special Scientic Newt relocation area Existing road network Interest (SSSI) Grade II* listed building Proposed drainage basin Existing walking, cycling and horse DEFRA Noise Action Planning Proposed drainage riding routes Construction compound Important Areas wetland habitat New walking and cycling routes Material storage / processing area River Tud and other Mattishall Lane Blind Lane m0 m005 watercourses Mattishall Parish Parish council boundary Construction works area © Crown copyright and database rights 2020 OS 100030649 4 5 6 7 8 9 Geology across the route The geology of the route is varied and may include: Alluvium Clay, silt, sand and gravel with localised peat River terrace gravels Sand and gravel The ground beneath our feet Lowestoft Formation In order to get a clear picture of the type of soils, rock types Glacial clay with sand and and groundwater levels, surveys will be carried out at a number cobble bands of individual locations across the proposed scheme area.
