Interchange (road)

In the field of road transport, an interchange or a grade-separated junction 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 junction without interruption from crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets.
The High Five in Dallas, Texas. This is a complicated five-level stack interchange, due to the proximity of frontage roads and segregated high-occupancy vehicle lanes. This hybrid design is based on parts of a four-level stack for highways, with a three-level-diamond interchange to handle the frontage roads. 32°55′27.2″N 96°45′50.0″W / 32.924222°N 96.763889°W / 32.924222; -96.763889
