Aqueduct Racetrack is going green.

The New York Racing Association began construction last week to remove the inner track and replace it with a second turf course, according to Daily Racing Form. The project should be completed for September training. In addition, the main dirt track will be renovated to allow winter racing.

The main track will consist of a limestone base and a sandy loam cushion, says Glen Kozak, NYRA’s director of racing surfaces.

“All we’re doing is putting in a limestone base, similar to what the winter track had or what the [Belmont] training track has,” Kozak told DRF. “The only thing that we’ll be doing to the cushion is add clay to hold moisture and tighten the track up.”
