One of the weaknesses is that because of its design of two beams supported by varied types of supports on either end, it usually cannot be very long, although there are some exceptions.
no weaknesses
An example of a beam bridge is Chesapeake Bay bridge-tunnel Site: http://www.pbs.org/wgbh/buildingbig/bridge/index.html

It is a beam bridge

2 strengths are that 1) Very easy to construct 2) Great for short distances 1 weakness is that 1) cannot be very long
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.

Well with a beam it allows the bridge to support the bridge

The first beam bridge was built in America
The Banpo Bridge is a girder bridge.
Arch bridge: the span beam of bridge is the shape of an arch & the load is diverted in compressive method. Beam bridge: the shape of beam span is of simply supported or continuous. here the load is diverted through bending compression method.
