Seagull intersections get their name from the pattern that the two right-turn lanes make when looking down from the air.
Seagull intersections allow one direction of traffic to travel straight through without stopping. Those wishing to turn right into the side road at the intersection simply bear right into a separate lane, which forms one 'wing' of the seagull. Here, they meet the opposite carriageway and the side road. Traffic wishing to turn right out of the side road, simply cross the intersecting carriageway and drive up the other 'wing' of the seagull, and merge onto the other carriageway.
Seagull intersections may have a second smaller seagull formed by two left turning lanes into and out of the side road.
Different methods are used to control traffic where two right-turning movements and the through movement meet. Most intersections use traffic lights, while others use Give Way and Stop signs, and sometimes roundabouts.

Famous quotes containing the word design:
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
