HCC officials comment:

Just so you are aware Batchwood Drive is about to be closed by the water
company under an emergency closure due to a burst water main. They will
put the closure, diversion route and all traffic management in place. The
diversion route will be Verulum Road, Folly Lane, Catherine Street, St
Peters Street and Harpenden Road. I have spoken to our control centre and
can confirm the diversion is on a salting route.

At this stage I cannot say when the road will reopen, but I will update you
again as soon as I have anymore information.
