Many tourists have visited Towe Bridge. It was the only bridge over the river Thames that can open and let ships pass under it. Towe Birdge was built in 1894 and still uses the same machines to lift up the two halves of the bridge. In early time, the river was much busier than now and the bridge had to open over a thousand time a year. Today, it only opens twice a week.In 1952, a big red bus was in the middle of the bridge when it started to open. The driver only just got to the other side in time! Of course, now there are lights at each end and the traffic must wait for them to go green.
