Most of the artificial-turf surface for a new, interim sports field has been rolled out on Pier 40’s inner courtyard. New lights for nighttime use have also been installed. The strips of FieldTurf still need to be sewed together and a mix of sand and rubber pellets still needs to be poured onto it to provide give and cushioning. There won’t be any locker rooms built on the pier at the end of W. Houston St., but bathrooms will be available for clothes changing. The sports facility is slated for an early-January opening, with a gala ribbon-cutting ceremony set for spring. Permits have been distributed for use by local youth and adult leagues until the spring season, when new permits will be issued.
