A toll bridge is a bridge where drivers must pay a fee, known as a toll, to cross. This fee helps cover the costs of building, maintaining, and operating the bridge. Toll bridges can be found in many places around the world and often have booths or electronic systems to collect payments. The toll amount can vary based on factors such as vehicle type and time of day. Some well-known examples of toll bridges include the Golden Gate Bridge in San Francisco and the George Washington Bridge in New York City. These structures are essential for connecting different regions and facilitating transportation.
