Red Hook may be a little less isolated by fall with the proposed extension of the B77 and B71 buses to South Ferry in Manhattan via the Brooklyn Battery Tunnel. The changes could make life easier for some people hit by the planned closing of the Smith-9th Street station. The B77 bus runs from Park Slope to Red Hook and the B71 runs from Crown Heights to Cobble Hill. The plan will be up for financial review in April.–NYDN
