The "Land Bridge" was a theoretical "ice bridge" between East Russia and Alaka which enabled the Native Americans to travel to America. It was caused because of the most recent Ice Age because the Arctic Ice advanced to the Bering Strait (the body of water that currently seperates Alaska and Russia). There is no Land Bridge now because when the Ice Age ended the ice melted , which left only water.
Or Bering Strait was submerged by waters from melting glaciers after the ice age. Since no humans were there back then or there to record and study the land we really have no idea what happened but what i just gave you is the assumption that many geologists have made about the whole affair.
A span on a bridge is the distance between supports such as from pier to pier. A bridge can have several supports over its length. A bridge length includes the entire bridge.
The pros are that the cantilever bridge is the only bridge that only has one supporting object.The other side is free.
The Brooklyn bridge was designed by John Roebling and the Roeblings helped in the process of building the bridge with many other workers.
Asia via the Beringea land bridge across what is now the Bering Straits. So much water was locked up in glaciers at the time that sea levels were low enough to expose the sea floor of the Bering Sea as dry land.
