The tunnel passed through a narrow section of hill beneath the sprawling network of flues and conveyors leading from smelter operations to the emissions stack. A Save the Tunnel Facebook campaign was launched but support failed to materialize even from a Ruston town historian Karen Pickett who was quoted regarding removal, from a practical standpoint, it is a difficult spot, so I think its probably a good thing, and it's a gain (for the town).
Demolition had been tied up in legal limbo as developers of the billion dollar redevelopment, Point Ruston, had issues regarding financial solvency and a labor dispute. These have for now been resolved and the project and a new route of Ruston Way is proceeding. Their planned method entails packing the tunnel full of dirt to then remove the roof and wall sections. The idea is that this way they will not damage the railroad portion still currently in use as the fill dirt will act as support. The fill will mostly be removed afterwards.
