Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a grade separation [1] [2] or as an interchange – in contrast with an intersection, at-grade, a diamond crossing ...
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
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 crossing of freeways by other routes is typically achieved with grade separation either in the form of underpasses or overpasses. In addition to sidewalks (pavements) attached to roads that cross a freeway, specialized pedestrian footbridges or tunnels may also be provided.
A more technical term is "grade-separated junction". A burrowing junction or dive-under occurs where the diverging line passes below the main line. The alternative to grade separation is a level junction or flat junction, where tracks cross at grade, and conflicting routes must be protected by interlocked signals.
Work on the $24.7 million RM 620 Roundabout Project began in 2020 and was completed this week. It is intended to improve safety, enhance mobility in west Round Rock.
Rapid transit systems use complete grade separation of their rights of way to avoid traffic interference with frequent and reliable service. Railroads also use balloon loops and flying junctions instead of flat junctions, as a way to reverse direction and to avoid trains conflicting with those on other tracks.
Grade (fasteners), the grade of nuts and bolts refers to the strength and material; Grading (earthworks), the preparation and leveling of land for construction, especially of roads and railways; Grade separation, aligning a junction of two or more transport axes at different heights to facilitate traffic flow
