  2. Cloverleaf interchange - Wikipedia

    en.wikipedia.org/wiki/Cloverleaf_interchange

    A cloverleaf interchange is a two-level interchange in which all turns are handled by slip roads. To go left (in right-hand traffic; reverse directions in left-driving regions), vehicles first continue as one road passes over or under the other, then exit right onto a one-way three-fourths loop ramp (270°) and merge onto the intersecting road.

    A partial cloverleaf interchange or parclo is a modification of a cloverleaf interchange. The design has been well received, and has since become one of the most popular freeway -to- arterial interchange designs in North America.

    The cloverleaf interchange between US 131, M-6 and 68th Street in Cutlerville, Michigan, United States, shows many of the features of controlled-access highways: entry and exit ramps, median strips for opposing traffic, no at-grade intersections and no direct access to properties.

  5. Interchange (road) - Wikipedia

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

    A partial cloverleaf interchange (often shortened to the portmanteau, parclo) is an interchange with loops ramps in one to three quadrants, and diamond interchange ramps in any number of quadrants. The various configurations are generally a safer modification of the cloverleaf design, due to a partial or complete reduction in weaving, but may ...

    Diamond interchange; Partial cloverleaf interchange; Single-point urban interchange; Roundabout interchange; Compact grade-separation, whereby the two roads are linked by a compact "connector road", with major-minor priority junctions at each of its ends; usually a variant of the cloverleaf type interchange, but only involving two quadrants ...

    A two-level interchange in which turns are handled by eight total ramp or slip roads, four of which form loops that give the interchange the shape of a cloverleaf from the air. Each ramp allows traffic from one direction of a roadway to access only one direction of the crossroad: e.g. from northbound to eastbound while a separate ramp connects ...

  8. Local–express lanes - Wikipedia

    This interchange is unusual because it also allows traffic to flow directly between SR 41 and SR 168 bypassing SR 180, making it in effect a double braided ramp. www.dot.ca.gov Google Maps: Florida: I-295: Jacksonville: Between Collins Road and Roosevelt Boulevard/US-17: 3.4 miles (5.47 km) Georgia: I-85: Gwinnett County: Exit 104 – Exit 109: ...

  9. Road hierarchy - Wikipedia

    Bundesautobahn 9 near by Garching bei Muenchen, Germany. At the top of the hierarchy in terms of traffic flow and speed are controlled-access highways; their defining characteristic is the control of access to and from the road, meaning that the road cannot be directly accessed from properties or other roads, but only from specific connector roads.
