Baldock already suffers from congestion due to medieval town centre; large lorries cutting through from A1 to A505 colliding on numerous ccasions with the railway bridge and causing damage to properties on the White Horse crossroads junction. Increasing the size of the town by 73% will exacerbate these problems and cse problems on all surrounding roads with increased traffic volume. Rail company is proposing to increase journey times to London by 20 minutes. Trains are often full at Letchworth during rush hour so knock on effects for other stops will be profound.
