I'm planning a ride from the Manhattan West Side bike path up and over to the zoo.
Here is my planned route. PLease let me know if any of this is not feasible or wise -- especially the bridge at 207th/University Heights, or Fordham Rd.
Up above the George W. Bridge, above Fort Tryon Park:
Rt on Dyckman
Left on Broadway
Rt on W 207th
Cross the bridge
becomes W Fordham/E. Fordham Rd.
Rt on E 188 St.
Rt on Beaumont Ave
L on E 187
R on Southern Blvd which is the outline of the zoo.
