Highway features are important components of any roadway system. Lanes refer to the individual strips of pavement that make up a highway, allowing for multiple lanes of traffic to travel in the same direction. Ramps are sections of road that allow vehicles to transition from one level of a highway to another, such as an exit ramp from a highway to a local road. Overpasses are elevated sections of highway that allow vehicles to pass over other roads or railways without having to stop.
