Biggleswade and Sandy drivers warned of further A1 delays today
There are delays of around 40 minutes on the A1 southbound today (February 6) due to utility works between Biggleswade and the A1M at Baldock.
This is due to Anglian Water carrying out emergency repair works.
The closure will be in place until at least this afternoon.
