Bridges in the United States serve as vital connections for transportation, allowing vehicles and pedestrians to cross rivers, valleys, and other obstacles. There are over 600,000 bridges across the country, ranging from small footbridges to large structures like the Golden Gate Bridge in San Francisco and the Brooklyn Bridge in New York City. These bridges vary in design and materials, including suspension, arch, and beam types. Many bridges are maintained by state and local governments, ensuring safety and accessibility for millions of users each day. Regular inspections help identify necessary repairs and upgrades to keep these structures functional.
