Toll gates are structures located on roads or bridges where drivers must pay a fee to use the route. This fee, known as a toll, helps fund the maintenance and construction of the roadway. Toll gates can be manned by attendants or automated, allowing for electronic payments through systems like E-ZPass. Toll roads are often used to manage traffic and generate revenue for transportation projects. They can be found in many countries and are common on highways, bridges, and tunnels. The amount charged at a toll gate may vary based on factors such as vehicle type and distance traveled.
