Ipswich Northern Route, Stage 1 Study Interim Report. (2016/2017)
The study was funded in partnership with the Suffolk district and borough councils. This work forms part of the Suffolk County Council’s commitment to short, medium and long term plans to improve transport in the wider Ipswich area to address existing congestion and to accommodate future planned growth in and around the town.
A package of proposals to improve the A14 junctions around Ipswich is also being developed by the county council working alongside Highways England. The first stage of the northern routes study considered the transport conditions across the wider Ipswich area both now and in 2031, based on current planned growth and identified highway improvements, including the Upper Orwell Crossings.In addition to these improvements there is likely to be a need for significant additional road capacity in the area to support future growth.Highway options for consideration in the next stage of the study include:
- single and dual carriageway roads, potentially with a strategic function to relieve the A14;
- full relief road primarily to serve local traffic demand; partial relief roads to connect areas of potential development to the main road network;
- and local distributor roads to spread traffic across the network.
Initial broad route corridors have been considered for a potential link between the A12 and A14; and are:
- an inner corridor from Martlesham to Claydon
- an middle corridor from Woodbridge to Claydon
- and an outer corridor from Melton to Needham Market.
Preliminary traffic modelling has indicated that roads in each of these corridors would have different effects on traffic e.g. an outer corridor would have more benefit to longer distance trips than trips more local to the Ipswich area.Each potential corridor would also have different impacts on the environment, and on the potential to support future growth.The next stage of study will examine route options in more detail, including traffic, economic and environmental impacts. It will also consider the extent to which the options might support potential future scenarios for housing and employment growth beyond 2031.
