I received the following yesterday:
“Please be advised that National Grid will be carrying out works to repair a gas leak at the above junction this weekend. We understand the leak has been on National Grid’s log for a while and repairs need to be carried out as a matter of urgency.
Due to location of the works it will be necessary to deploy four way temporary traffic signals at the junction. All approaches to the junction will be narrowed down to single lanes. Works start on Saturday morning at 8am and it is anticipated the works will be finished and temporary signals removed by 6pm on Sunday evening at the latest.”
