Mead Street which runs along the Green River once was a short cut fom Mill Street to Deerfield Street Rt 5 &10. Today the North half of this road is open to vehicular traffic lower South end only to foot traffic. There are dams/waterfalls on the upper and lower ends of this street. Worth checking out if time allows and there is interest.
