Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will (a) set out the data sources, supporting information and the assumptions used and (b) estimate traffic volumes per (i) day and (ii) peak hour for (A) Option A14 and (B) Option C of the Lower Thames Crossing Option on (1) the existing Dartford Crossing, (2) a new Option A14 crossing, (3) a new Option C crossing, (4) the A282 between junction 30 and junction 2 of the M25, (5) the A2 between the M25 and the A227, (6) the A2 between the A227 and the M2, (7) the A227 between the A2 and the A20, (8) the A228 between the M2 and M20 and (9) the A229 between the M2 and the M20.

a) The data sources, supporting information and assumptions used in Highways England’s traffic modelling have been set out in the Pre-Consultation Scheme Assessment Report which is available on the Lower Thames Crossing public consultation website.

b) The estimate of traffic volumes requested for Option A14 was aggregated in terms of changes in traffic flows across the network, and then compared with other options (including Option C) in terms of overall economic performance. Consequently the breakdown of traffic volumes is not currently held in the form requested. The estimate of traffic volumes for selected links for Option C is reported in the Pre-Consultation Scheme Assessment Report.
