Suffolk County Council has announced plans for a £63m highway improvement scheme along the A12.

First proposed in 2020, the plans have since been adjusted following two public consultations. The council said it will formally submit the full planning application to its planning directorate on 14 November.

Stretching between the A12/A14 Seven Hills junction and Woods Lane junction, the project includes a range of improvements to the 6.8-mile stretch of carriageway:

  • Highway upgrades to improve traffic flow and safety, including enhancements to seven road junctions
  • Construction of a mobility hub at Adastral Park, designed to support sustainable travel options and improve public transport integration
  • Replacement of the Martlesham footbridge with a new non-motorised users bridge to improve accessibility for pedestrians and cyclists
  • New signalised bus link junction north of Anson Road, connecting the A12 and Main Road via Portal Avenue
  • Dual carriageway upgrade between the A12/B1438 Ipswich Road junction and the A12/B1079 Grundisburgh Road junction, including a new layby, shared use footway/cycleway, and agricultural accessway
  • New shared use footway/cycleways at Portal Avenue and north of A1152 Woods Lane, along with improved crossing facilities at key junctions
  • Additional highway features, such as maintenance bays, traffic signs, upgraded signals, and pedestrian crossings.

The aim of the works is to improve 'connectivity, safety and accessibility' for all road users along the route.

Cllr Chris Chambers, Suffolk County Council Cabinet member for transport strategy, said: ‘This council is committed to enhancing local infrastructure, aiding sustainable economic recovery and developing growth. These proposals are a transformative infrastructure investment which reflect the council's dedication to improving regional mobility, reducing congestion, and promoting sustainable transport.'
