Concern has grown in recent years over the seismic activity of the New Madrid seismic zone in Western Kentucky. Graves County, Kentucky is located in this region. To permit emergency medical, supply, and equipment traffic into this area after an earthquake has occurred, the Kentucky Transportation Cabinet is interested in the possibility of keeping selected routes passable. This report lists the routes that have been investigated and recommended as being the routes in Graves County that should be maintained in a passable condition. The recommended routes, KY 94, KY 121, KY 58/KY 80, US 45/KY 58, US 45, and KY 58, have been visually surveyed and all seismically significant features cataloged. These features are logged by their location on strip maps contained in Appendix A and a detailed listing of all the potentially critical features is given in Appendix B.
