In December of 2003 there was a possible close call (the driver called this in to our office <br /> on 12-10-03). We suggested to the railroad stop and flag this crossing (in lieu of AFLS&G) but they <br /> are not willing, so we have to install AFLS&G's. <br /> Railroad needs to cut the trees and brush in the NE and NW quads. They also need to remove and <br /> replace the asphalt transition strips adjacent to the rubber crossing surface, as they are deteriorating <br /> and causing a rough ride. The east ped asphalt also needs to be repaired. <br /> Page three will be the Location Sketch (Aerial Photo) of the crossing. <br />
