Answer:
Railroads and bridges are both types of transportation infrastructure, but they serve different purposes and have different characteristics. Here are two differences between railroads and bridges:
Railroads:
Railroads are a means of transportation for goods and people that run on tracks, while bridges are structures that allow for travel over bodies of water, valleys, or other obstacles.
Railroads require specialized trains to run on the tracks and follow a specific path, while bridges can be crossed by a variety of vehicles, including cars, trucks, and pedestrians.
Bridges:
Bridges are designed to span a gap or obstacle, while railroads are designed to provide a specific transportation route.
Bridges come in many different types and designs, including suspension, cable-stayed, and arch, while railroads generally follow a similar track layout and design.
