As part of the A55/A494/A494 Flintshire Corridor Study, the economic assessment identified that the Red Route would deliver £423.5m of benefits over a 60 year period. This assessment took into account travel time and accident benefits. The delivery of this scheme therefore will bring significant benefits to the area and reduce the existing congestion costs.
