What's A Spooey?


Everybody knows what a cloverleaf looks like, but could you identify a Lofthouse, a ParClo, a Butt, a Spooey, or a Braid? These are among the distinctive designs that transportation engineers have conjured up to keep traffic flowing and motorists headed in the right direction when major roads intersect.

For your driverly edification, The Infrastructurist compiled photo examples of more than 20 different kinds of strange and delightful highway interchanges found both in the US and abroad.

Can't believe there's a whole class of interchange named after one I drive on every day. Lofthouse has changed a lot since that photograph was taken. And it still doesn't work right. Low capacity is right. Every evening rush hour the southbound on ramp (bottom left in the picture) grinds to a complete halt.

A lesson in how not to build a highway interchange.

Sorry - bottom left should read bottom right. Still thinking I should drive on the right.
