The protected bike lane on Broadway is impassible, forcing cyclists to veer dangerously into the street. This is unacceptable to have a bike lane completely covered in ice, especially as Cambridge touts itself as a bike-friendly city. Further up the street, the sidewalk level bike lane has had snow pushed into it and has aso not been plowed. The bike lane on the other side of the street is also full of snow. This is unacceptable!
