What it was
A proposed pedestrian bridge and landscaped garden across the River Thames between Temple and the South Bank.
The project gained a design team, charity, planning permissions, public funding commitments and private fundraising. Its procurement, operating assumptions and exposure of taxpayers to future costs became increasingly contested.
Existence timeline
A planted pedestrian bridge is advanced for central London.
Transport for London selects a design team and development accelerates.
Planning approvals and major public commitments move the scheme closer to delivery.
A review questions value, transparency and the remaining funding gap.
The trust ends the scheme after guarantees and viable delivery conditions fail.
Why it ended
The Mayor declined to provide the guarantees required for construction, planning permission approached expiry and the Garden Bridge Trust closed in 2017.
Last confirmed trace
Public reviews, procurement records, planning documents and expenditure reports preserve an unusually detailed account of the cancelled bridge.
What it left behind
The failure became a major British case study in public-project governance, transparency and the cost of cancelling before construction.
How we classified it
The proposed archive unit never reached ordinary public access in the form being documented.
The strongest verified milestone maps to approved_or_funded under Arrival Score V1.
