This stretch of pavement would test the patience of a saint. At random times throughout the day or week--say, 8 p.m. on a Sunday or 10 a.m. on a Tuesday--drivers face the kind of stop-and-go traffic usually associated with grisly car wrecks. The cause of this particular headache is that the Crosstown narrows from three lanes to two, and just one of these is reserved for drivers heading into Minneapolis. While inching along this asphalt-paved patch of Hell, the image of a watermelon being forced into a Coke bottle comes readily to mind.
