the beam bridge and... i am not sure of the other one
The early bridges that were built by early man were the log bridge. That is a a log was thrown across a river to cross.
The most common types of straight bridges used in civil engineering projects are beam bridges, truss bridges, and arch bridges.
The most common materials used in bridge building are generally steel or concrete for larger bridges, and stone or wood for smaller bridges.
they used arches for their bridges and other things such as aqueducts they are still standing today well most of them
Most bridges are manmade, built in the location where they are required. Some natural bridges of rock or timber exist in wilderness areas.
There is no average length. They are built to suit local conditions.
We watched a video about bridges in school today. :) I'd say that the most primitive were simple stepping stones, and fallen trees.
According to Wikipedia, six of the longest bridges are located in China, and three in the US, in the state of Louisiana. Read more, below.
Steel is the most common, especially for suspension bridges. Concrete is used for lower bridges (and where little shifting will occur) because it is more resistant to the elements.
Most bridges are not built with boards, and those which are built with boards usually have straight boards, not crooked boards. However, there is a lot of stress placed on bridges by the vehicles that pass over them, and boards could certainly be pushed out of position.

Lots and lots of things. Most common things he did include the Clifton suspension bridge, built the first iron ship, built many bridges. The main reason he is so well known and was rated the 2nd best Briton ever is because he started the industrial revolution.
