Mr. Patrick Klaers <br />December 10, 1996 <br />Page Four <br /> <br />A large percentage of the cost associated with the construction of a pedestrian overpass <br />with structural ramps, is the cost of the ramps themselves. As can be seen from the above <br />cost breakdown, the cost for a pedestrian overpass with embankments and a pedestrian <br />underpass are comparable. <br /> <br />Both pedestrian crossings are feasible from an engineering standpoint. However, several <br />issues would need to be resolved prior to deciding on a style or type of grade-separated <br />pedestrian crossing. Aesthetics become an issue when considering a pedestrian overpass <br />as well as cost. Safety and drainage issues become a concern when considering a <br />pedestrian underpass. <br /> <br />A third option would be to redefine the at-grade crossing of CSAH 1. It is unlikely that <br />at-grade pedestrian crossings of CSAH 1 at the trail location could ever be eliminated; <br />therefore, with the reconstruction of CSAH 1, proper signing and striping could be <br />installed to warn motor vehicles of the potential hazard. In addition, trails could be built <br />alongside CSAH 1 to allow crossing at the intersection of CSAH 1 and County Road 77. <br />This is an intersection that we believe will warrant signalization within the foreseeable <br />future. This may afford a safe means for at-grade crossings of CSAH 1. <br /> <br />Please let me know if you would like us to do any additional work on this issue. <br /> <br />Sincerely, <br /> <br />MSA, CONSULTING ENGINEERS <br /> <br />Terry ~..
