Photograph of the Everett Covered Bridge, which crosses Furnace Run. Covered bridges are truss bridges with support coming from a framework of beams. The builders of Everett Covered Bridge used a truss pattern patented by Robert W. Smith of Tipp City, Ohio, in 1867. The bridge was also unlikely to have been built much after the 1870s. The popularity of covered bridges waned in the 1880s with the appearance of more durable iron bridges like the one seen at Station Road Bridge Trailhead. Everett Covered Bridge was repaired at least twice after major damage, first caused by the 1913 flood and then by a truck in 1970. Then in 1975, rushing water from a spring storm lifted the bridge from its sandstone abutments and deposited the wreckage into the stream bed below.
