Conclusion
Bridges have been constructed from prehistoric times. From simple logs to the more elaborate structures built in by the Romans. The advancements in math, physics, and technology have helped modern man attain near impossible goals. Bridges are not only bigger than that of the past, but are lighter, cheaper and built faster than those of the past. If we continue our current trend in the advancements of technology, who knows what feats we can do a hundred years from now.
