So they could remain on the island for the remainder of their sentence. And if they attempted to escape, they would have to cross the sea to get to mainland; so they'd probably be dead even if they escaped Alcatraz and tried to swim away.
First of all, you don't swim from Alcatraz and live. The ocean currents are so severe that they will tear your clothes right off.
It can be from 1 1/4 to 1 3/4 miles, depending on the currents. Swimmers range in age from 10 to 85 minutes long.
It was considered escape proof because it was in the middle of the San Francisco bay. It was thought that if anyone did escape the prison, it would be impossible to swim all the way to the mainland. The only two prisoners to actually get off the island are claimed to have drowned.
Alcatraz Island does not have a bridge connecting it to the mainland. It is primarily accessed by ferry services from San Francisco. The island is famous for its former prison, and while there are other bridges in the area, such as the Golden Gate Bridge, none connect directly to Alcatraz.
