The longest flyover in the United States is the Judge Harry Pregerson Interchange in Los Angeles, California. It is a complex network of flyovers and ramps that serves as a major transportation hub in the Los Angeles area, connecting the Harbor Freeway (Interstate 110) with the Santa Monica Freeway (Interstate 10). The flyover is approximately 5.5 miles (8.9 kilometers) long and was completed in 1993. It is named after Judge Harry Pregerson, a former federal judge who was instrumental in the development of the project. The flyover was designed to improve traffic flow and reduce congestion in the heavily populated area it serves.
Bridges are man-made constructions used to bridge rivers, lakes, mountain ranges, highways, or any other obstruction in the way of roads, trails, or trains.
