The Sands Street path runs from Navy Street to the foot of the Manhattan Bridge at Jay Street.
This afternoon the DOT press office emailed a brief reply to our query about potential safety enhancements to the recently opened Sands Street bike path. They say some details of the path, which is rideable for cyclists, are in progress:
This project is still ongoing. As we continue to implement the improvements, we will be certain to make any adjustments necessary to facilitate bikers getting to and from the bridge.
The question we sent was specifically about the traffic signal at Jay and Sands, and whether an exclusive phase for cyclists might be added. Seems like they're still evaluating the options.
