Have you ever driven through an intersection and wondered how this came into being? I recently drove through Natick, MA and came across this lovely intersection. It's like two streets intersecting with a rotary on top of the whole mess. There were at least four traffic lights trying to regulate the flow of traffic.
It makes this intersection by my parents' house seem sane.
reveilles has fond memories of Kelley Square in Worcester, MA. Notice the six roads feeding into the wide expanse of asphalt in the center of the map: Green St., Harding St., Madison St., Millbury St., Vernon St., and Water St.
Does anyone else have other good examples of dumb street design?
