An elevated roadway is a type of road that is built above the ground level, often supported by columns or pillars. This design helps to reduce traffic congestion on the streets below and allows for smoother vehicle flow. Elevated roadways are commonly found in urban areas where space is limited and can connect different parts of a city efficiently. These structures can also minimize the impact of traffic noise and pollution on surrounding neighborhoods. Examples of elevated roadways include the High Line in New York City and the Skyway in Minneapolis. They are essential for modern transportation systems, providing a practical solution to urban mobility challenges.
