The proposed pipeline appears to cross the Potomac near the mouth of the South Branch. It's hard to determine from the tiny map shared by the gas company whether it crosses the South Branch or travels east of the river to Levels.
The terrain map below shows that there are possible routes along the North Branch floodplain, French's Station Road, or along the South Branch meander that creates the French's Neck West / Blue Meadow's North floodplain.
This seems like an opportunity for planners and our government leaders to negotiate a better bridge crossing at Oldtown/Green Spring, or possible road improvements wherever the pipeline travels.
