The Art of Freeway Exchanges


From The Infrastructurist:

Everybody knows what a cloverleaf looks like — but could you identify a volleyball, a double trumpet, or a “spooey” if you drove on one in the course of your highway travels? 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, we’ve compiled photo examples of more than 2o different kinds of strange and delightful highway interchanges found both here in the US and abroad. In fact, right now stimulus dollars are being spent t0 build or upgrade many interchanges into one of these forms.

Part 1 and Part 2 are both worth perusing for the highway porn.  Also, it should be worth noting that The Infrastructurist has quickly become one of my favorite new reads.  A nice specific topic that they cover so well.  [via Boing Boing]
