Glenloch Interchange

Glenloch Interchange is Canberra's only major interchange which connects Tuggeranong Parkway with Parkes Way, William Hovell Drive and Caswell Drive. Following a major reconstruction lasting from 2007 to mid-2008, the interchange now operates without traffic lights. A surprising feature was the retention of an unused bridge from the previous alignment which led from the centre of the Parkes Way/Caswell Drive loop, passing east over two northbound roads, before petering out to the east. This was finally removed in late 2010 during roadworks to upgrade the new interchange to dual carriageway standards.

Seven Dials

Seven Dials is a small road junction in Covent Garden in the London Borough of Camden, West End of London where seven streets converge. At the centre of the roughly circular space is a column bearing six sundials, a result of the column being commissioned before a late-stage alteration of the plans from an original six roads to seven.

Michigan left

A Michigan left is an at-grade intersection design that replaces each left turn at an intersection between a (major) divided roadway and a secondary (minor) roadway with the combination of a right turn followed by a U-turn, or a U-turn followed by a right turn, depending on the situation.

All-way stop

An all-way stop is an intersection system used predominantly in the United States of America, SADC, Liberia and Canada where traffic approaching it from all directions is required to stop before proceeding through the intersection. An all-way stop may have multiple approaches and may be marked with a supplemental plate stating the number of approaches.

A jughandle is a type of ramp or slip road that changes the way traffic turns left at an at-grade intersection. Instead of a standard left turn being made from the left lane, left-turning traffic uses a ramp on the right side of the road. In a standard forward jughandle or near-side jughandle, the ramp leaves before the intersection, and left-turning traffic turns left off it rather than the through road. Right turns are also made using the jughandle.

Hook turn

A hook turn is a road cycling maneuver and traffic-control mechanism in which vehicles that would normally turn from the closest lane of an intersection instead turn from the farthest lane, across all other lanes of traffic.

Hollywood and Vine

Hollywood and Vine, the intersection of Hollywood Boulevard and Vine Street in Hollywood, a district of Los Angeles, became famous in the 1920s for its concentration of radio and movie-related businesses. The Hollywood Walk of Fame is centered on the intersection.

Continuous-flow intersection

A continuous flow intersection (CFI), also called a crossover displaced left-turn, is an alternative design for an at-grade road junction. Vehicles attempting to turn across the opposing direction of traffic cross before they enter the intersection. No left turn signal in the intersection is then necessary. Instead, vehicles traveling in both directions can proceed, including through vehicles and those turning right or left, when a generic traffic signal/stop sign permits.

Scotch Corner

Scotch Corner is an important junction of the A1(M) and A66 trunk roads near Richmond in North Yorkshire, England. One of the best-known junctions in the country – it has been described as "the modern gateway to Cumbria, the North East and Scotland" – it is a primary destination signed from as far away as the M6 motorway. The junction's name is derived from the fact that it is the point of divergence for traffic coming from London, the East Midlands, and further south in Yorkshire and wishing to continue either to Edinburgh and eastern Scotland or to Glasgow and western Scotland.

Traffic circle

A traffic circle is a type of intersection that directs both turning and through traffic onto a one-way circular roadway, usually built for the purposes of traffic calming or aesthetics. Contrary to a roundabout, where entering traffic always yields to traffic already in the circle and merges in directly, the entrances to traffic circles are three-way intersections either controlled by stop signs, traffic signals, or not formally controlled. Colloquially, however, roundabouts are sometimes referred to as circles.
