COORDINATION AND COMMENTS ........................................................................................... 1 APPENDICES Appendix A - Figures Appendix B - Correspondence and Report Coordination Appendix C - Public Involvement ii EXECUTIVE SUMMARY The proposed project would construct a fourteen-foot wide multi-use trail and pedestrian bridge over the Chattahoochee River in Fulton County, Georgia, between the cities of Roswell and Sandy Springs. The pedestrian bridge would be parallel to, but detached from, the northbound State Route (SR) 9 bridge crossing the river at the same location. The pedestrian bridge would include refuge areas and pedestrian lighting. The multi-use trail and pedestrian bridge would be constructed within the SR 9 right-of-way over the river on the north side. Additional right-of-way and easement would be required from the south side of the river. To aid construction, temporary rock jetties would be constructed from each bank of the river. Only one jetty would be constructed at a time, and each would extend approximately halfway across the river. Parks, recreation areas, restaurants, retail facilities, and office buildings are abundant near the river in both cities, in addition to numerous apartment complexes and residential subdivisions. Connectivity between these land uses across the Chattahoochee River is currently
