The tunnel will be located 60 to 70 feet underground. The access for the excavation necessary for the tunnel will be at a single, central point along the approximately one mile route of the tunnel. As a result, the excavation will not require trenching. Further, individuals on the surface will likely not realize excavation is taking place far below them.
