In Option B, what is the additional cost of upgrading the road between TH roundabout and the new
roundabout west of TH roundabout to dual-carriageway?
The additional cost of widening this section of the A46 to dual carriageway is included in the Option B cost estimates that have been produced by National Highways, but they do not provide cost breakdowns for individual sections.

Transport modelling will be updated during the next stage of the project (option selection). This will include extension of the forecasting period beyond 2041 and will take account of the emerging plans for Garden Communities. More detailed operational assessment network performance would also be undertaken, which could result in refinements to the proposed highway layout for the options.
