OXFORD The cars hum and the trucks rumble along on Route 31, unaware that a mid-1800s railroad tunnel right under the highway is returning to nature collapsing from age, erosion and lack of repair.
Route 31 is the only north-south state highway in mid- and western Warren County and provides a connection between Interstates 80 to the north and 78 to the south. The road is the key to the controversial development of several warehouse projects on what were once thriving farms.
As the highway winds its way south from the hamlet of Oxford once called Oxford Furnace it passes over the shoulder of Oxford Mountain, and directly over a 160-year-old, now-abandoned railroad tunnel.
