a arch bridge can hold over 6,000 pounds
Bridges are able to hold so much weight because of the way they are built and the tension that holds them together
4 GODS SAKE PEOPLE!! IT WEIGHS A LOT !! :p
Yes, it does. Part of its strength comes from the use of flying buttresses as added support. Typically, pointed arches are used to support thinner walls for aesthetic purposes, but can handle increased overhead weight.AnswerI'm almost positive that it does. I think it is the keystone (very center stone in a rounded arch) that is the downfall of a rounded arch. This only holds so much weight. I believe that the pointed arch holds most of its weight on the "legs"

it can't hold very much weight
Total weight of the steelwork: 52,800 tonnes including arch and steel approach spans. Weight of the arch: 39,000 tonnes.
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.
The simple arch (barrel arch) was invented by the Etruscans. The Romans developed a more complex arch, the vaulted arch. The vaulted arch, combined with the development of a type of concrete which was much superior than that of other civilisations, facilitated the construction of large scale building and bigger bridges. Roman bridges crossed much wider rivers and valleys and much deeper valleys. In the case of deep valleys, two or three rows of arches were built on top on each other to make the bridge taller. Roman concrete also set underwater and was used to build much bigger docks for ports. Concrete also made it possible to build much bigger and sophisticated domes compared to those of other civilisations. The the aqueducts were another very important innovation.
20 times its weight in liquid
112lbs
it can hold as much weight as it can handle
There is effectively no limit to the amount of weight that aluminum can hold, if you use enough aluminum.
