DOT’s recent design tweaks to Eighth Street have come with an unwelcome change on Fifth Avenue. As the Fifth Avenue bike lane approaches Eighth Street, it now morphs into sharrows that overlap with a turning lane for motorists. The dedicated space for cycling is gone, and the new design is incompatible with the protected bike lane that advocates and the local community board have called for on Fifth Avenue.

While the southern end of Fifth Avenue doesn’t carry much car traffic, as the street approaches its terminus at Washington Square Park, many drivers turn left onto eastbound Eighth Street. The left-side bike lane was sacrificed to make way for a new design to handle this turning traffic.

The intent of the design is to separate the turning motorists from people crossing Eighth Street, who now have “a split-phase leading pedestrian interval,” giving them a head start before drivers receive a flashing yellow turn arrow. But it also calls for cyclists to do a non-intuitive merging movement around turning drivers, including many MTA buses and tour buses. Since bus drivers swing right before making tight left turns, the bike stencils direct cyclists to take a path that could conflict with the path of buses.

An earlier version of the plan, presented to Manhattan Community Board 2 last November, added the turn lane but kept the bike lane [PDF].

DOT says it will finish markings and signal work by the end of the month.

More than a year ago, DOT committed to studying protected bike lanes on Fifth Avenue and Sixth Avenue, in response to local elected officials and community boards, but hasn’t produced anything since then.

This section of Fifth Avenue, with its low volume of traffic, would be an ideal location to begin building out protected lanes on these important north-south streets. With its corner sidewalk extensions, however, the new intersection design won’t work with a protected bike lane:
