The Caerphilly Interchange Project comprises the procurement of a single Design and Build contractor to deliver the redevelopment of Caerphilly railway station and adjoining bus interchange into a modern, fully integrated multi‑modal transport hub. The works include demolition of existing infrastructure and construction of a new interchange facility incorporating rail, bus, taxi and active travel connectivity, alongside enhanced passenger amenities, retail space, and public realm improvements. The scheme forms a key component of wider regeneration ambitions and the South Wales Metro programme. The project will directly impact transport users, local residents, and businesses across Caerphilly and the wider Cardiff Capital Region, improving accessibility, passenger experience and sustainable travel options and is expected to support economic regeneration and modal shift. ## CPV classification Railway station construction work Construction work for railways and cable transport systems Construction work Engineering design services Source Find a Tender (UK) · Notice ocds-h6vhtk-05dd7c-2026-07-17T16:09:13+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-05dd7c-2026-07-17T16:09:13+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
