What are beams on bridges?
In its most basic form, a beam bridge consists of a horizontal beam that is supported at each end by piers. The weight of the beam pushes straight down on the piers. The beam itself must be strong so that it doesn’t bend under its own weight and the added weight of crossing traffic.
What is a famous example of a beam bridge?
An example of this is the world’s longest continuous-span beam bridge. The Lake Pontchartrain Causeway in Louisiana is almost 24 miles long. It’s a pair of two-lane sections that run parallel to each other. The south-bound lane, finished in 1956, is made up of 2,243 separate beam bridge spans.
What is the name of the beam bridge?
Beam Bridge is also known as the Girder Bridge. The main aim of constructing a bridge is to provide passage of traffic from one end to another end. Beam Bridges are the simplest structural forms for the spans of the bridge which is supported by the abutments or piers at each end.

How many types of beam supports are there?
In engineering, beams are of several types: Simply supported – a beam supported on the ends which are free to rotate and have no moment resistance. Fixed or Encastre – a beam supported on both ends and restrained from rotation. Over hanging – a simple beam extending beyond its support on one end.
