Engineering clarity shaped into a living, connected landscape
Turweston Green Overbridge
The Turweston Green Overbridge is conceived as a quiet, continuous plane of landscape drawn across one of HS2’s deepest cuttings - reconciling large‑scale engineering with the subtleties of landform.
Its 99‑metre span, carried on a disciplined arrangement of 36 paired steel beams, establishes a structural rhythm that is legible yet understated, allowing proportion and clarity to guide the expression rather than ornament or spectacle.
The bridge’s generous 5,940 m² deck, designed to receive 2,700 cubic metres of earth, becomes a sculpted terrain rather than an object, extending hedgerows and planting across its width to maintain the continuity of fields, habitats and local routes. This approach allows the engineered elements to recede beneath a grounded, landscape-led form—an architectural decision that acknowledges both the physical scale of the HS2 corridor and the visual delicacy required at its interface with rural settlements.
