To ask the Scottish Government what assessment has been made of the present capacity of the A1 south of Dunbar, and what its position is on its suitability for the amount of HGV traffic that (a) currently uses the route and (b) is estimated to use the route in the future.Transport Scotland works with road Operating Companies and Local Authorities to continually monitor usage and performance of the Trunk Road Network, this data feeds in to the Transport Model for Scotland (TMfS) and various regional transport models. These are used on an ongoing basis to assess performance of the network in current and estimated future conditions. Figures for traffic currently using the A1 from the National Traffic Data System (NTDS) count site at Grantshouse show a daily average traffic flow of 9,113 vehicles in 2019 with an average of 15.6% HGVs (approximately 1,400 HGVs per day).

This shows that currently less than one fifth of vehicles at this count site on the A1 are an HGV. Analysis undertaken previously as part of the Borders Transport Corridors Study did not identify an issue with unsuitable proportions of HGV traffic at this location, and indeed found that HGV traffic on the A1 had reduced by 2% between 2010 and 2016, despite increases on other trunk roads in the area.

Transport modelling to assess current performance and predict future use is currently being undertaken as part of the emerging Strategic Transport Projects Review. STPR2 is ongoing, therefore is not possible to take a position on the future suitability of particular (sections of) roads until the modelling being used to inform the appraisal process is completed.
