UPDATE: the roads are now open 😀
Please note, Annables Lane is completely closed at the junction with Kinsbourne Green Lane.
There really is no way through.
Traffic is being diverted down Kennels Lane, a single track lane. So if coming to Harpenden from the M1 junction you’d be advised using the Redbourn bypass and Redbourn Lane (despite temporary traffic lights causing delays there).
Kinsbourne Green Lane West is also closed.
The sign says this will be in place until tomorrow, 3rd October.
