Bridge Project 2: Increasing our knowledge about bridges.

After writting what we know about bridges, we have to obtain more information about bridges, and the biggest source of information is internet, so we go to the computer's room to search in internet. We've got some pages where we can search the information, but we've got to select the correct information, because there's so much information in internet so it's necessary to select the information, and resume it with more common words.
