The Hudson River Greenway in NYC is the MOST widely used bikelane in the USA.

And there are some low-hanging fruit to improve access to it.

This short clip shows how easily this Hudson River Greenway could be connected to the mezzanine of Riverside Park in Morningside Heights (~Upper West Side near Columbia University, Manhattan, NYC near Broadway and 125) by simply changing a single double-wide, under-utilized exit ramp of the adjacent Car Road - Henry Hudson Parkway.

Exit 12N of the Henry Hudson Parkway could be a bike lane for the cost of a few concrete barricades. It would harden bike access by providing for a parallel path.

And it wouldn't even inspire ire w car drivers since no cars would lose parking or even be made to wait at a stoplight.
