A bridge far too low...

This was the scene after a bus driver ploughed a double-decker into a low bridge, ripping the roof off.

The No 75 was severely damaged after the female driver took an unauthorised detour in south-east London in a bid to make up time. She had earlier been involved in another collision, hitting a bus and causing minor damage. The passengers had to get off and take a different bus.

When the replacement vehicle arrived, the driver was ordered to return to Catford garage. Finding herself behind schedule, she took a detour often used by single-deckers. But one bridge in Sydenham was too low and the top sheared off, causing £50,000 damage in the accident last week. No passengers were on board.

The driver, who has not been named, was in shock but declined medical treatment. She was suspended and later decided to resign. Stagecoach said: "An internal investigation is ongoing."
