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 ...
The bridge pattern is a design pattern used in software engineering that is meant to "decouple an abstraction from its implementation so that the two can vary independently", introduced by the Gang of Four. [1] The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes.
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 ...
Bypassing a crash at the bridge; Allowing an oversize load to bypass a low bridge; Some factors make turning left onto a diverging diamond interchange from the highway ramp more hazardous: 1) There is a yield sign instead of a traffic light. 2) The driver can not see if the light for the through traffic is red or green.
It also includes the Chicago, Milwaukee and St. Paul Railroad Grade Separation, which comprises 30 bridges built over the Milwaukee Road tracks one block north of Lake Street in Minneapolis. [1] The submission traces the historical context of reinforced concrete bridge building in Minnesota and cites examples of early and historic bridges. [2]
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.
In all cases one road crosses the other via a bridge or a tunnel, as opposed to an at-grade crossing. The inter-connecting roads, or slip-roads, which link the two roads, can follow any one of a number of patterns. The actual pattern is determined by a number of factors including local topology, traffic density, land cost, building costs, type ...
