What we are doing
We wrote to you in September about our gas main diversion works on College Crescent and Alexandra Road. These works were expected to be complete on 26 October 2025. These works are now due to finish on 12 December 2025.
We halted works across the London tunnels sections of the route following a serious incident at our site at Green Park Way. No works took place on College Crescent and Alexandra Road between 8 and 17 October 2025. Works have now restarted following a comprehensive review of safety procedures and leadership.
In addition, we are required to do a redesign of our programme as the location of the gas main does not match the utility company records.This has also impacted our programme. We are carrying out additional excavation works within our works area to finalise our design.
We apologise for any inconvenience these works may cause.
HS2 is undergoing a comprehensive reset to ensure it can be built efficiently and for the lowest reasonable cost. This work is being carried out in stages and will be completed in 2026. We will provide you with updates on the reset and what this means for our plans to build the railway in your area.
