 Until recently, all four quadrants were occupied by gas stations, adding frequently-used exit and entrance ramps to the mix of multi-directional traffic.The gas station in the southwest quadrant has been demolished, its footprint being filled in with green space; the one in the northeast quadrant is now occupied by an AT&T telephone store.The gas station in the southeast quadrant is the only one still in regular use, as the gas station in the northwest quadrant has been permanently closed.
