Engineers working overnight at Tower Bridge
City Bridge Foundation owns and manages five bridges across the River Thames in London. The five bridges are Tower Bridge, London Bridge, Southwark Bridge, Millennium Bridge and Blackfriars Bridge.
Our bridges form a critical part of London’s transport infrastructure, help keep the capital moving and support its role as a global capital of business, culture and tourism.
Each year we spend around £30m to ensure our five bridges are in tip-top condition for the tens of thousands of people who cross them every day. Our bridges are maintained and repaired at zero cost to the public taxpayer.
Where possible, we will highlight upcoming works and closures to the five bridges on this webpage.
