NOEL KING, HOST:
Good morning. I'm Noel King. The Tower Bridge in London is a century-old drawbridge that opens to let tall ships pass through. Yesterday, it opened and then did not close. Owing to a technical failure, it was stuck that way for a few hours, closed to cars and pedestrians trying to cross the River Thames in central London. A nurse on her way to work tweeted slight pause to my walk, but it was cool to see the bridge open for the first time in my life. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
