Just an update.

On the way to work I get off the manhattan bridge, make a right on canale and a left onto Allen. Allen turns into 1st Ave and I take that all the way up to 47th and I cut across to park.

On the way home I just take 46th to 2nd and take 2nd all the way down. There is a bike path on the left side of 2nd south of 14th st. South of Houston 2nd turns to Christie St and takes you all the way to the Manhattan Bridge, Christie St has bike paths on either side.

Thanks for all the help.
