What is the Toston Bridge?
The Toston Bridge is a strong bridge made of steel. It has three main sections, called spans, that connect together. These sections are built using a design called a Warren truss. A truss is a framework of connected triangles that makes the bridge very strong.
How Was It Built?
This bridge is a through truss bridge. This means that cars drive through the main structure of the bridge, not over the top of it. The steel parts are held together with rivets, which are like strong metal pins.
The bridge stands on two big supports in the river, called piers. These piers are made of reinforced concrete, which is concrete with steel bars inside to make it extra strong. The ends of the bridge also rest on reinforced concrete supports called abutments.
Bridge Dimensions
The Toston Bridge is quite long! It measures about 525 feet (or 160 meters) from one end to the other. Each of its three main sections is 175 feet (about 53 meters) long.
