Yes, but the bridge depends on its age. The older it is, the weaker the bridge is. The younger it is, the STRONGER the bridge is.
yes it would be EXPLAIN IDIOT!

They are less likely to be hit by waves Short span beam bridges are very strong.
The different between suspension bridge and beam bridge are beam bridge are for short distance but suspension bridge for long distance. Beam bridge are used for highway passes and suspension bridge for wide waterway passes.
Danyang-Kunshan Grand Bridge is the longest beam bridge in the world and is approx 164.8 kilometres long.
beam and tunnel
An example of a beam bridge is Chesapeake Bay bridge-tunnel Site: http://www.pbs.org/wgbh/buildingbig/bridge/index.html
Arch bridges are in the shape of an upside down "U" with mainly steel beans, while supension bridges have one or two Major verticle beams with strong wire connecting to the bridge.
As strong as you make it... Basically a truss system is used when a beam cannot hold its load, so is one way of 'reinforcing' a beam (you could have more supporting colums or use cable stayed/suspension techniques). Its basically stronger than a beam, and 'weaker' than a suspension bridge, but to be honest it's basically as strong as you engineer it. Try searching truss bridge on wikipedia... there's lots of different types and I'm sure it'l have the info.
beam bridge
Well with a beam it allows the bridge to support the bridge
