Design a bridge to span a river with a width of 100 meters, capable of supporting vehicles weighing up to 20 tons. The bridge must be economical, structurally sound, and aesthetically pleasing. Consider factors such as material strength, cost, environmental impact, and construction time.
Tasks:
Determine the most suitable bridge type for the given scenario (e.g., beam bridge, truss bridge, arch bridge, suspension bridge).
Calculate the load-bearing capacity required for the bridge based on the maximum vehicle weight and traffic conditions.
Select appropriate materials for construction, considering factors like strength-to-weight ratio, cost, and durability.
Design the structural components of the bridge, including the deck, supports, and any additional features required for stability.
Evaluate the environmental impact of the proposed design and suggest mitigation measures if necessary.
Estimate the total cost of construction, including materials, labor, and maintenance over a specified lifespan.
Create detailed engineering drawings and specifications for the proposed bridge design.
Present your design rationale, including analysis of alternative approaches and their respective advantages and disadvantages.
