The first keystone arch railroad bridges built in America are wholly dry laid, and range in height to 70 feet. They made possible the construction of the Western Railroad, the longest and highest railroad in the world in 1840.
The Keystone Arch Bridge Trail starts at a stone bridge, still carrying trains. The twisting path then leads under a concrete arch with trains to arrive at two magnificent granite arches bypassed by the 1912 line relocation,70 and 65 feet overhead. The trail then leads through a concrete arch beside a stone bridge, giving a tunnel effect, ending at the only double arch bridge in the series, also in use by the railroad.
