A turnpike is a type of road that requires drivers to pay a toll for usage. These tolls help maintain the road and fund its construction. Turnpikes can be found in many countries and are often designed for high-speed travel, connecting major cities and regions. Historically, the term "turnpike" originated from gates that were turned to allow passage only after a toll was paid. Today, many turnpikes use electronic toll collection systems, allowing vehicles to pass without stopping. This system improves traffic flow and reduces congestion on busy routes, making travel more efficient.
