The stated completion date is subject to change as line closure dates for Gateshead have not yet been confirmed. For the purpose of this notice, should Nexus proceed with the Gateshead works, it is assumed works will take place during a February 2027 closure with follow-up works in March 2027. Exact details will be confirmed within the tender documents when released. Chillingham Road works will be undertaken during a 54-hour line closure between 24 and 26 October 2026.
