This model successfully worked to hold desired load and effectively fulfilled the load resistance qualities that a practical bridge must have. Keywords Truss bridge, bridge competition, bridge model, bridge stability. Introduction Bridge design is the fundamental part of civil engineering and most critical as well. It is designed for transportation of heavy traffic; meanwhile, it is constructed to cope with environmental effects like storms. There are many types of bridges that are being used around the world, among them most common are arch bridges, girder bridges, truss bridges, cantilever bridges, cable stayed bridges, moveable bridges and suspension bridges(SWE, 2012). The type of bridge that we incorporated in our design is the truss bridge. These are the oldest and the most economical bridges found around the world with excellent weight bearing capacity(BuildingBig, 2010). Atypical truss bridge is shown below: Specialty of truss bridges is the triangular elements present in the structure to share the load applied on the bridge by the traffic(JHU). In a typical truss bridge design the horizontal members are responsible for bearing loads as a result of horizontal as well as dynamic compression.
In our bridge design we made use of Popsicle sticks to create truss members as well as the base of the bridge. These sticks were joined together by making use of glue. Where required, the sticks were cut to the required lengths for making triangle structures of the bridge. For providing strength to the design, the sticks were stacked over each other in 3 to 4 layers and the whole structure was made which is shown below: Before finalizing the above bridge design, we tested a number of bridge structures before as well by making use of west point bridge design, but all those designs failed while testing. By making use of strategic techniques to design practical bridges based on load distribution errors were reduced and thickness of trusses and other members was increased. This gave stability to the bridge design. After that we started working in the structure of the bridge. For that purpose the first task was to select the appropriate material for constructing truss bridge which goes well with our dimensional requirements. Therefore, popsicle sticks were chosen as a preferred material. After that all the sticks were marked at the point of applying glue. Initial step was to design the the bottom frame of the structure in which three layers of sticks were used. Here is the view of one bottom structure. Total two rails were made for the bridge. After structuring the bottom next step was to structure the rectangular truss portion of the bridge. For that purpose first two steps of bottom design were used; to collect popsicle sticks and gluing them together. After that, triangular portions were structured and joined together. These trusses were then connected to the bottom rails as shown below: Last step was to connect the assembly of both the trusses and bottom rails to each other by making use of popsicle sticks and gluing them to the bottom. In this way the final structure was drawn. Results and Discussion In the design of first bridge, total 145 popsicle sticks were used and the resulting weight of the bridge was calculated to be approximately 198.3lbs.

Frankford Avenue Bridge (Pennsylvania)
After many years, the route through the bridge transformed into a major traffic route. In 1740, the bride was widened to accommodate heavy traffic which originally had a length of 73 feet and a width of 18 feet. Because of changes in the transportation mode and traffic flow, there was need for the bridge to be renovated (Philadelphia City Archives 45).
