In general, the first phase should run from the center of the Northbank (say Bay & Newnan) to Five Points or even Park & King in Riverside. Water Street/Independent Drive through DT, Park or Myrtle down to Forest, Riverside, Post and then Oak.
Such a path would directly hit the Landing, Laura Street, Omni, MODIS, Hyatt, Bay Street District, Times Union Center, CSX, Water Street garage, Prime Osborn, Brooklyn, 200 Riverside, Everbank, Fidelity, LPS, BCBS, Cummer, Five Points/Margaret St, St. Vincents, Park & King and all the houses, condo towers and apartment complexes in between.
