Reflecting on the London Bridge Collapse: 36 Years On
London, 15 January 2026 – Thirty-six years ago, on 15 January 1990, the iconic London Bridge natural limestone arch along Australia’s Great Ocean Road unexpectedly collapsed, reshaping perceptions of coastal geology and tourism in Victoria.
Background of the Formation
London Bridge, located just beyond Port Campbell in Port Campbell National Park, was a striking natural wonder formed from limestone over centuries. Shaped by relentless wind and waves eroding weaker layers, it featured a double-span arch connected to the mainland. Visitors once walked or drove across the eastern span, marvelling at its archway form before the collapse.
The Collapse Event
On the afternoon of 15 January 1990, the span closest to the shore suddenly collapsed into the sea. Two visitors, stranded on the outer span, were rescued by helicopter in a dramatic global news event. The incident highlighted the dynamic and impermanent nature of coastal landscapes, where natural forces can alter formations in an instant.
Key Facts
| Aspect | Details |
|---|---|
| Location | Port Campbell National Park, Victoria, Australia |
| Date of Collapse | 15 January 1990 |
| Cause | Erosion by wind and waves weakening the limestone structure |
| Impact | Rescue of two visitors; symbol of coastal impermanence |
Legacy and Tourism
Today, the site remains a popular tourist attraction, with upper and lower viewing platforms offering sweeping vistas of the collapsed arch and coastline. The lower platform, though steeper and uneven, provides wheelchair access via a sealed path. Visitors can also observe little penguins returning to shore at dusk, with a colony of 80–100 penguins nesting nearby. The collapse serves as a reminder of nature’s power and the need for responsible tourism in fragile environments.
Frequently Asked Questions
What caused the London Bridge to collapse?
The collapse resulted from natural erosion, where wind and waves gradually weakened the softer limestone layers beneath the arch, leading to the sudden failure of the span closest to the shore.
Were there any casualties?
No fatalities occurred, but two visitors were stranded and required helicopter rescue. The event underscored the risks of exploring dynamic coastal formations.
How has the site changed since 1990?
The collapsed arch now stands as a testament to geological processes, with viewing platforms added for safe observation. Tourism continues, focusing on education about coastal erosion and wildlife.
