Midtown Manhattan avenues have a problem: The sidewalks aren't wide enough for all the people walking on them. People have to walk in the roadbed to get where they're going. On avenues with protected bike lanes, this means people on foot spill over into bikeways, rendering them all but impassable for cyclists. Now there's a single Midtown block with a protected bike lane that also has a wider sidewalk.
Ever since DOT added a two-way protected bike lane around the northern and eastern edges of Union Square last year, the project has been marred by NYPD parking near the intersection with 15th Street. Plastic posts were supposed to keep cars out where police park, but it looks like DOT has jettisoned that idea and has no plans to revive it.
