For green tourism to take off in Southern Maryland, we should re-make our main river crossings, including bike/walk access on the bridge decks and paddle launch access below. In particular, the Thomas Johnson Bridge (Route 4 in Solomons, MD) and the Route 231 Bridge, which connects Prince Frederick in Calvert County with Hughsville in Charles County, need to become scenic tourist-friendly routes for bike riders and hikers. Solar ferries connecting key points on either side of the river should also be considered!
