Overnight Roadworks on A5 outside Birch Coppice Estate causing 1.5 hour delay getting off industrial estate

The planned overnight roadworks that started on 17/10/19 are causing major delays exiting Birch Coppice Industrial Estate. Last night it was taking staff, and HGV's exiting to make overnight deliveries over 1.5 hours to exit the industrial estate. As a business operator on the estate this has had major impact on our business as we despatch over 100 HGV's through the night all of which are now late. Can this please be looked at urgently and adjustments made to allow traffic to flow freely. The delays started at 00:00 and lasted until 05:00.
