A temporary detour along the Hudson River Greenway in Washington Heights went into effect Thursday.
The closure, related to work on the George Washington Bridge, will reroute cyclists to Broadway and Ft. Washington Avenue between 158th and 181st Streets. According to a Port Authority flier [PDF], pedestrians may access the park and riverfront through the tunnel at 172nd Street.
Interruptions are to occur on a "periodic" basis until December 31, "typically" from 7 a.m. to 6 p.m.
