The wall and trough are also an engineering example of the Floto Brothers' regionally known \"granolithic\" concrete. The form finds no other known Floto work using the material in a similar way.","narrative":"Old Market Street in Steubenville is a stretch of abandoned roadway about 1,150 feet long, with an ornamental retaining wall and water trough beside it. The street was paved with Belgium Block in 1909, chosen because its coarse surface gave horses better footing on the steep Market Street hill. Asphalt covered it in the late 1950s, though excavations suggest the original pavers survive below. In 1910 the Floto Brothers Construction Company built the 80-foot wall and trough about halfway up the grade so that horses hauling heavy wagons could drink and rest. Its precast \"granolithic\" concrete panels, fluted pilasters, lion's head spout and shell basin remain, though weathered. A spring once fed the trough. Circus caravans, including horses and elephants, stopped here on the way to the hilltop. The property was listed for its place in the city's transportation history and as an example of the Floto firm's concrete work.","period_of_significance":"1909-1942","architect_builder":"Floto Brothers Construction Company","architectural_style":null,"criteria":["A","C"],"status_note":"Old Market Street has been closed to the public since State Route 43 was built in 1973.
