An example of the potential complexity of grade separation, seen in the Jane Byrne Interchange in Chicago Seven various overpasses for grade separation in Spain near Barcelona Rail-rail grade separation in Xiaoshan, China The concept of grade separation includes all transport modes, such as a simple pedestrian bridge over rail tracks.
An overpass, called an overbridge or flyover (for a road only) in the United Kingdom and some other Commonwealth countries, is a bridge, road, railway or similar structure that is over another road or railway. An overpass and underpass together form a grade separation. [1] Stack interchanges are made up of several overpasses.
A grade-separated junction is a transport junction where at least one bridge or tunnel is used to separate traffic flows (known as grade separation). Relevant articles include: Road interchanges, known as grade-separated junctions in the UK; A flying junction, a type of grade-separated junction found on railway lines
The Fort Street Viaduct, which stretches 2,800 feet (850 m) in length and includes an 80-foot (24 m) roadway, was by far the largest and most ambitious structure included in the 1920s grade separation plan. [3] This bridge exemplifies the importance attached to the grade separation program, as planners tried to increase vehicle safety and ...
In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through ...
The interchange between I-35E and the Sam Rayburn Tollway in Lewisville, Texas, although similar in design to five-level stacks elsewhere in Texas, also qualifies as a six-level stack, since the ramp connecting the eastbound Sam Rayburn Tollway with northbound I-35E goes over the fifth-level ramps connecting I-35E in both directions with the ...
Some countries, such as the United States, allow for limited exceptions: some movable bridges, for instance the Interstate Bridge on Interstate 5 between Oregon and Washington, do require drivers to stop for ship traffic. The crossing of freeways by other routes is typically achieved with grade separation either in the form of underpasses or ...
The basic structure was built in 1903, and was the third railroad bridge on the site since 1863. It was raised in 1912–1914 as part of a grade separation project. The bridge's function was to carry Panhandle Route passenger, mail and express trains from Pennsylvania Station in
