Follow Broadway until you reach a set of lights and a paved, tree-lined footpath on your right called the Mid-block Connector (sign will also say “Ames Street”). This is not a street but a pedestrian footpath. Take right onto the path, and at the end of path, cross over Binney Street and take left onto Binney after crossing.
