The state line ceased operation in 1868 and was not resumed except for a brief period in 1874. The steep grades crossing the Blue Mountains made the route impractical. The growth of Summerville peaked in 1889 when the town boasted two flour mills, a bank, four merchandise stores, a drug store, a brewery, a butcher shop, three dressmaking shops, a hotel, one restaurant, two blacksmith shops, four sawmills, and three churches. Today the town is a small residential area set in a beautiful corner of the valley where deer and other wildlife thrive.
