There are already tailbacks at the Whitehorse Street junction and if BA1 contains 2800 more households, the traffic flow through this junction will increase significantly. The plan mentions that BA1 site is big enough to support a new link road, including an additional bridge over the railway, but the sustainability assessment does not assess what is needed. The Transport Assessment does not consider N of Baldock, only Baldock WITH Letchworth in traffic modelling. Local Plan Model Testing 60271338 says in para 2 Baldock and Letchworth have not been tested to date.
