Bicyclists will travel up the Henry Hudson Parkway from West 79th Street, cross the Henry Hudson Bridge, exit at Mosholu Parkway, make a U–turn at West Gun Hill Road and return southbound along the same route.

The West Side Highway will also be closed northbound from West 56th Street to the Henry Hudson Bridge.

Motorists should use an alternate route during this period and expect delays.
