Jay,
Just a thought... Where Rt4 meets Rt7 at Cornwall Bridge is not the covered bridge which cornwall is noted for. That's in West Cornwall. That being said, it might be more interesting for those that haven't seen the bridge to go Rt4 to Rt128 through the bridge then down Rt7 through the Housatonic State Forest. There's a restaurant just before the covered bridge that is good for eats and would provide good photo opps. of the bridge.
