How Often Does Tower Bridge Open?

About 800 Times a Year—A Few Per Day

Tower Bridge opens approximately 800–1,000 times annually, averaging 2–3 lifts per day (not 5—historical data shows lower recent frequency).

Patterns

• Seasonal: More in summer (tall ships, festivals).
• Scheduled: Published 24h+ in advance on towerbridge.org.uk.
• On Demand: 24-hr notice required for vessels >9 m mast/air draft.
• Duration: ~5–10 minutes per lift (raise, transit, lower).

Why Not More?

Road traffic priority (40,000 vehicles/day). Lifts coordinated to minimize disruption. Most commercial traffic uses downstream docks (Tilbury, London Gateway).

Check the schedule—watch a lift from the walkways or riverbank. It's Victorian clockwork in action.
