A toll booth is a structure located on a road or highway where drivers pay a fee to use that particular route. The fees collected help maintain the road and fund transportation projects. Toll booths can be manned by attendants or automated, allowing for electronic payments. Toll booths are commonly found on turnpikes, bridges, and tunnels. They can vary in design, from simple gates to more complex systems that include multiple lanes. Some regions use transponders for automatic toll collection, reducing the need for stopping and speeding up traffic flow.
