The Department of Transportation's proposal for a new bike lane in Brooklyn is spinning some community tension. The path, designated for Plaza Street West, would connect Prospect Park West with Park Slope and Prospect Heights. Transportation officials say the street's width allows for a two-way bike path, parking lanes on either side and a travel lane. While some residents say the lane should be moved out of the street and onto the sidewalk, others say the street is wide enough to include all bikers, cars and pedestrians. Members of Community Board 6 have voted to approve the plan.
