In the middle distance is one of the hundreds of arch bridges that knit the dozens of Venetian islands into a city. These bridges constitute a formidable obstacle for anything on wheels, which explains why Venice was never overrun by cars. Today, these bridges make the city nearly totally inaccessible for someone in a wheelchair and considerably hinder the passage of freight on handcarts. When designing new carfree cities, we must make certain not to repeat this mistake.
