Cycling

At 623 feet, this is the longest tunnel on the Montour Trail and has lights on throughout the year to help see your way. During the winter, the two entrances are sealed to prevent the buildup of ice, which could reach 2-3 feet thick due to the high moisture dripping from the walls and ceiling. Trail users can still enter the sealed tunnel via doorways throughout the winter and find a balmy interior. The tunnel was bored in 1913 and lined with concrete in 1928. Operations ended in 1980 and it became part of the Montour Trail in 1992.
