<P> On interchanges with U-turns, traffic intending to complete a left turn must either pass the interchange, make a U-turn and then exit right, or exit right first and then make a U-turn . </P> <P> There is a rarely used, unnamed type of interchange using a grade - separated design, similar to the at - grade design known as a "synchronized split - phasing intersection". It is somewhat like the diverging windmill except that left turn exits use left directional ramps, which, as with the diverging windmill, merge on the left . One such interchange formerly existed between Interstate 95 and I - 695 north of Baltimore, which has since been replaced by a four - level stack . There are few of these "synchronized split - phasing" interchanges, including one in Birmingham, Alabama between I - 65 and I - 20 / I - 59, locally called Malfunction Junction . A variation of this type exists in Grand Rapids, Michigan between Interstate 196 and US 131, where only the opposing carriageways of US 131 cross over each other, while the carriageways for I - 196 do not cross over, but pass through the interchange on different levels . </P> <Ul> <Li> <P> Divided volleyball Similar: 39 ° 02 ′ 25" N 94 ° 40 ′ 22" W ﻿ / ﻿ 39.040319 ° N 94.672888 ° W ﻿ / 39.040319; - 94.672888 19 ° 05 ′ 14" N 98 ° 12 ′ 21" W ﻿ / ﻿ 19.087282 ° N 98.205712 ° W ﻿ / 19.087282; - 98.205712 </P> </Li> <Li> <P> Full diamond Samples: 42 ° 21 ′ 33" N 83 ° 04 ′ 35" W ﻿ / ﻿ 42.359067 ° N 83.076425 ° W ﻿ / 42.359067; - 83.076425 35 ° 27 ′ 38" N 97 ° 34 ′ 32" W ﻿ / ﻿ 35.46046 ° N 97.575638 ° W ﻿ / 35.46046; - 97.575638 </P> </Li> <Li> <P> U-turns Samples: 37 ° 33 ′ 36" N 127 ° 04 ′ 19" E ﻿ / ﻿ 37.559940 ° N 127.072071 ° E ﻿ / 37.559940; 127.072071 42 ° 08 ′ 10" N 72 ° 37 ′ 33" W ﻿ / ﻿ 42.136216 ° N 72.625723 ° W ﻿ / 42.136216; - 72.625723 </P> </Li> <Li> <P> Current design of Knooppunt Vaanplein, Netherlands, location: 51 ° 51 ′ 56" N 4 ° 30 ′ 54" E ﻿ / ﻿ 51.865678 ° N 4.515036 ° E ﻿ / 51.865678; 4.515036 </P> </Li> </Ul> <Li> <P> Divided volleyball Similar: 39 ° 02 ′ 25" N 94 ° 40 ′ 22" W ﻿ / ﻿ 39.040319 ° N 94.672888 ° W ﻿ / 39.040319; - 94.672888 19 ° 05 ′ 14" N 98 ° 12 ′ 21" W ﻿ / ﻿ 19.087282 ° N 98.205712 ° W ﻿ / 19.087282; - 98.205712 </P> </Li>
