  2. Diamond interchange - Wikipedia

    en.wikipedia.org/wiki/Diamond_interchange

    A dumbbell interchange along Ontario Highway 401 in Clarington, Ontario, Canada.This one features a loop ramp. The ramp intersections may also be configured as a pair of roundabouts [1] to create a type of diamond interchange often called a dumbbell interchange [citation needed] (due to its aerial resemblance to a dumbbell), and sometimes called a double roundabout interchange.

  3. Diverging diamond interchange - Wikipedia

    en.wikipedia.org/wiki/Diverging_diamond_interchange

    A diverging diamond interchange (DDI), also called a double crossover diamond interchange (DCD), [1] [2] is a subset of diamond interchange in which the opposing directions of travel on the non-freeway road cross each other on either side of the interchange so that traffic crossing the freeway on the overpass or underpass is operating on the ...

  4. Three-level diamond interchange - Wikipedia

    en.wikipedia.org/.../Three-level_diamond_interchange

    A three-level diamond interchange is a type of highway interchange where through traffic on both main roads is grade-separated from intersections which handle transferring traffic. [1] It is similar in design to a three-level stacked roundabout except for its use of (usually signalled) conventional intersections , and can be thought of as two ...

  5. Single-point urban interchange - Wikipedia

    en.wikipedia.org/wiki/Single-point_urban_interchange

    A single-point urban interchange (SPUI, / ˈ s p uː i / SPOO-ee or / ˈ s p juː i / SPEW-ee), also called a single-point interchange (SPI) [1] or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space efficiently.

  6. Interchange (road) - Wikipedia

    en.wikipedia.org/wiki/Interchange_(road)

    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.

  7. Partial cloverleaf interchange - Wikipedia

    en.wikipedia.org/wiki/Partial_cloverleaf_interchange

    A4 Interchange for right-hand traffic, or B4 interchange for left-hand traffic The parclo A4 (also called "six-ramp partial cloverleaf") contains six ramps. [ 2 ] On each side on the freeway, there is an (often multi-lane) exit ramp, followed by a loop ramp and directional ramp entering the freeway.

  8. Split intersection - Wikipedia

    en.wikipedia.org/wiki/Split_intersection

    Split intersection. A split intersection is a rarely-built at-grade variant of the diamond interchange. [1] Compared to a conventional four-leg intersection or road crossing, the arterial road is split into separate carriageways by 200 to 300 feet (61 to 91 m), which allows a queue of left turning vehicles behind a completed turn into the crossroad without any conflict to oncoming traffic.
