Rocky Brook Park ?
East Windsor, Mercer County, NJ
115 acres along the Millstone River


The property borders run between the Millstone River and Rocky Brook from near the intersection of Old Trenton Road and One Mile Road eastward, then south along the Rocky Brook to the Hightstown Bypass. Acreage alongside the bypass from that point west to One Mile Road is also included in the plan.

From the New York City area: New Jersey Turnpike south to Exit 8; turn right heading west on Route 33; turn left onto Main Street and in a short distance take the next right onto Route 571 heading west; drive 0.8 of a mile and pass through the intersection with Route 130.  Drive about 0.2 of a mile more and just before the Target store turn right onto Lanning Drive.  In a block or so turn right heading to the Municipal Building.  At the circle around the building, drive about 2/3s of the way around the circle and park near the bike path on the left. 


$1 million grant from the Garden State Preservation Trust combined with a $500,000 grant already received from the Garden State Preservation Trust by East Windsor Green Space Inc., a private nonprofit agency devoted to preserving East Windsor open space.

The Rocky Brook Bikeway extends 3/4s of a mile from East Windsor Township Municipal Building to One Mile Road.

10/21/04.  There are a lot of dry fields along this bike path along with small patches of woods or woods edge.  On the far or not so far left are lots of apartment buildings.  The area opens up with apartments still on the left and a sound wall across the field on the right.  It's a good place to study dry fields and succession.  Dr. Patrick L.
