Bridges come in many shapes and sizes.
Each built to withstand the elements surrounding it.
Simple beam bridges, may only cross a stream or a gully too difficult to traverse, and are seldom longer than 250 feet.
A truss bridge is a superstructure meant to carry heavy loads.
A cantilever bridge stretches over the obstacle, is only attached on the ends, and raises in the middle to allow for larger loads to go UNDER.
An arch bridge carries the weight of traffic through the abutments on either side. These bridges are strong enough to carry trains.
Tied arch bridges, or bow string bridges are constructed a bit differently, and the weight is carried through tension in the bottom cord of the bridge.
Suspension bridges are suspended from cables. The earliest ones being ropes and vines. The cables hang from towers that are built deep into the ground below the bridge.
Cable-stayed bridges, like suspension bridges, are held up by cables, but have less cables, and taller towers.
But my very favorite bridge of all is the Gospel bridge. It’s the one that God provided for us. It is built with eternity in mind. It bridges a gap that I can’t jump. I’m thankful to have a path to choose. One that is strong enough to carry a load that I could never bare.
