Traffic in the capital was “gridlocked” after the bridge failed to close after allowing a ship to pass along the River Thames, the PA Media news agency reported. Queues of motorists and pedestrians waited for at least an hour, while police asked motorists to find alternative routes around the city.

Spanning the River Thames, the landmark, known as a “bascule” bridge (French for “see-saw”), was completed in 1894. Once powered by steam, the hydraulic bascules have been driven by oil and electricity since 1976.
