While the general layout of the town hasn't changed much over the last 50 years, one major event changed the character: the building of Rt. 290. In the sections where the highway overpasses could not be built, roads were either rerouted or cut in 1/2 and turned into cul-de-sacs. So if you are headed for an address on Howard Street, you'd best check a map first to see which end you have to get to first!
