M.J.MM Storm Sewer

In Urban Exploration - Drains/Sewers by Ronnie K

Drains McMechen respectively, including Mosher and John. Was relieved by Druid Hill/ North Avenue Intercepter. It varies in size from an arched culvert 12 feet wide and 15 feet high to a circle 4 feet 6 inches in diameter. Drains out the Rutters Run Lateral. An old, forgotten, buried yet ever present stream. Extensive system with 2 significant junction chambers. Extensive tunnel system draining an area that was notorious for small streams and springs. Exploration of these tunnels requires a man raft as it is block by a deep pit of water of unknown depth.
