Main Street Bridge

Information and Findings From Ohio's Historic Bridge Inventory

Setting/Context

The bridge carries a 4 lane street over a stream in downtown Mt. Vernon.

Physical Description

The 5 span, 190'-long stone arch bridge has coursed ashlar arch barrels and spandrel walls. Earlier railings were removed and replaced with concrete parapets with tubular handrails in 1969. The bridge has bullnosed stone piers with concrete scour protection added.

Integrity

Railing replacement (1969). Concrete toe walls/scour protection added around piers, 1969?

Summary of Significance

"The 1892 stone arch bridge has some alterations (railings, toe walls) but maintains it character defining features. There have been no significant changes in the bridge's status since the prior inventory. The eligible recommendation remains appropriate. Stone arch highway bridges and culverts are not uncommon in Ohio with more than 190 examples dating from ca. 1825 to 1940 (Phase 1A Survey, 2008). Significant examples date to the 2nd quarter of the 19th century (fewer than 26 pre-1851) and are often associated with historically important transportation routes such as the National Road and the state's early canals or railroads. Later examples may have significance on the merits of the aesthetic quality/craftsmanship of the masonry work or in association with parks, such as the stone arch bridges in Cleveland's Rockefeller Park (ca. 1897-1904) or Youngstown's Mill Creek Park (ca. 1913). Stone arch culverts have roadways on earth fill atop the arch, which may or may not have headwalls, but they are the same traditional technology as arch bridges that have spandrel walls and parapets. ""The immigrants who settled America came from European countries where masonry arch bridge construction was well established. Our most distinctive collection of stone arch bridges are found on the early, eastern trunkline railroads such as the B&O and Erie railroads. Early turnpikes such as the National Road had impressive stone arch bridges in Maryland. Along the road in Ohio, the famous S-bridges were built. Canals such as the Erie and the Chesapeake & Ohio had stone arch aqueducts. The technology of stone arch construction is ancient. Increased use of metal truss bridges from the late 1800s into the early twentieth century, led to a decline in stone arch bridge construction. The strength and durability of stone arch bridges made them popular. Generally, stone arch bridges built during the nineteenth century are found today in areas where good stone was available. Stone arches were common in the first half of the nineteenth century, and a number of these structures still exist. Stone arch bridges from the late eighteenth and first half of the nineteenth century are highly significant if they retain their character-defining features, which include the arch ring with keystone, barrel, spandrel wall, parapet, headwalls and abutments/wingwalls. Piers may also be a character-defining feature. Many of these stone arch structures possess both engineering and historical significance for their associations with the work programs of the Great 1930s. Stone arch bridges that do not fit within these areas (early, Depression-era, association with parks) generally possess less significance, but are still significant.""

Justification

A well represented bridge type throughout the state for both bridges and culverts, stone arch bridges date from the mid 1830s and the building of the National Road through Belmont Co. Many are superbly proportioned and constructed by local contractors. They were built through World War I, particularly during the later years in park settings. More than 125 examples remain. This example has moderate significance based on its date of construction, detailing, and historic contexts).
