A general view of the HS2/EWR interface area on November 29, 2023 looking west along EWR towards Bicester from Addison Road (bridge No. 27). The gradient up to the rail bridge taking EWR over HS2 can be seen, with the site of the future HS2 infrastructure maintenance depot on the right and the trackbed for the possible future EWR Aylesbury branch on the left.

AKEY stage in two major rail projects was reached on December 1 when HS2 contractors completed their responsibilities for the East West Rail route at the point where the two new lines cross in rural Buckinghamshire.
The handover gave the East West Rail Alliance (EWRA comprising Atkins, Laing O’Rourke, Network Rail and VolkerRail,) full control of its route from Bicester to Bletchley, thus allowing the final tracks to be laid connecting Oxford with Milton Keynes and Bedford.
HS2’s contractors EKFB (a joint venture between Eiffage, Kier, Ferrovial Construction and BAM Nuttall) had been responsible for building the section of EWR trackbed from just west of the former Claydon Crossing (at 11 miles 17 chains from Bletchley) to just east of bridge No. 29 (at 13 miles 39 chains from Bletchley). This section has been progressively released to the EWRA from Claydon towards Calvert since May, with December 1 seeing the final 420 yards (385 metres) handed over.
The work involved demolishing two road- over-rail bridges (Nos. 27 Addison Road and 28 Gawcott Road) and then building: A new road-over-rail bridge for Addison Road; a bridge for East West Rail tracks to cross HS2; and a rail-over-road bridge for Gawcott Road.
