Last month, a hit-and-run driver struck and killed Matthew von Ohlen while he was riding in the Grand Street bike lane in Williamsburg. Tomorrow night at a special meeting of Brooklyn Community Board 1, von Ohlen’s friends and family will ask DOT to explore upgrading Grand Street to a protected lane.
