4. Havengore Bridge update (05.02.21) Havengore Bridge remains closed to marine traffic. The contractors attended this week, ran a full diagnostic check and repaired the known issue. However, on completion of this work they identified an intermittent fault with a hydraulic valve. We are now awaiting the fault report and further information on next steps and estimated downtime which we will share when it becomes available. We apologise for the ongoing inconvenience and thank you for your patience. Nicki Uden – Community Liaison Officer, SHOEBURYNESS RANGE
