Just completed Oct 2005, built by Sloppy Sam & Breaking Ground Skateparks. Probably around 6000 sq. feet, maybe more. It is all concrete with a bowled/banked-in street area that opens to a super-tight backyard style pool with cast in place coping. Shallow end on the pool is 4', down to 8' in the deep end. Unfortunately, the street area has water coming from the base of the jersey barrier, which will have to be fixed in the spring. You can see it easily in the pics. Other than that, its super smooth and all the trannies are perfect. There are no fees, rules are posted - helmets required but nobody seems to wear them, and it is open year round. Bikes in the street area are a problem on busy days. Wethersfield is located just south of Hartford.
This is probably the best skatepark in Connecticut, despite the puddles.
