The Skate Park opened with grand fanfare and anticipation in May of 2004. Opening day video. Built by Grindline Skateparks, the Milltown Commons boasts a 7,000 square foot horseshoe shaped bowl with depths from four to nine feet. Elements include an over-vertical clam shell and bowl door. A 3,000 square foot street course has ledges, china banks, a manual pad, rails and more. Enjoyed by area youth and the young-at-heart, the Milltown Skate Park has become one of the most popular skate parks in the whole area.
