Details

These reports set out the work done as part of the A303, A358 and A30 corridor feasibility study.

The study aimed to identify opportunities and understand the case for future investment on the A303, A358 and A30 corridor.

The study was split into 3 stages, which were:

  • stage 1: review evidence and identify problems and issues
  • stage 2: finalise the range of proposals that could address the problems
  • stage 3: assess the affordability, value for money and deliverability of the proposals

The Department for Transport (DfT) commissioned this work and CM2HHILL conducted the analysis. DfT has provided an overview of the study which informed our ‘Road investment strategy’ (RIS) and particularly the ‘RIS investment plan’.
