They've already started on the new paths/lanes on my commute route, so I thought I'd start a thread for progress info regarding these changes.
I ride across W'burg bridge and down the E. River greenway to South Street Seaport.
On Manhattan side, there's a bike lane going down the middle of the road on the North side of the bridge (towards the E. River) which seems to just dump you into an access road.
They cut out a swathe the old erroded asphalt around the Fulton fish market and were laying nice smooth asphalt down today. Judging by the routing of the path there, it looks like they will install some barriers to separate the path from the open parking area.
