2. Design Objective Satisfy all of the specifications listed below, while keeping the total cost of the project as low as possible 3. Bridge Configuration 1. The bridge may cross the valley at any elevation from the high water level to 24 meters above the high water level. 2. If the elevation of the bridge is below 24 meters, excavation of the river banks will be required to achieve the correct highway elevation. 3. To provide clearance for overhead power lines (shown above), the highest point on the bridge may not exceed an elevation 32.5 meters above the high water level (8.5 meters above the top of the river banks). 4. The bridge may consist of either standard (simple supports) or (arch supports). If necessary, the bridge may also use one intermediate , located near the centre of the valley. If necessary, the bridge may also use cable, located 8 meters behind one or both abutments 5. Each main truss can have no morethan 100 and no morethan 200
