caption_attribution_description: English: The Stone Road Bridge spans the Eramosa River on Stone Road East, between Victoria Road South and Watson Road South, in the City of Guelph. The single-span concrete bowstring arch truss bridge was constructed in 1916.
context_page_description: The Eramosa River is a river in Wellington County in southwestern Ontario which rises near Erin, Ontario, and flows southwest through the city of Guelph, where it joins the Speed River, which then enters the Grand River in Cambridge. The river is believed to derive its named from the Mississauga word um-ne-mo-sah, meaning "black dog" or "dead dog".
context_section_description: A number of bridges have been built to cross the Eramosa River.
  The Guelph Junction Railway constructed a bridge over the river in 1888, at a site between Guelph's Royal City Jaycees Park (then known as "Paradise") and Victoria Park.
  A three-arched concrete bridge was constructed over the river in 1910 using penal labour from the Ontario Reformatory. A wooden trestle bridge was soon constructed to connect the small railway at the Rocks to the Ontario Reformatory by way of a branch line. The 12.2 metres (40 ft) Benham Bridge was also constructed in 1910 to bridge the Eramosa on Eramosa-Erin Townline Road.
  MacQuillan's Bridge, a 21.3 metres (70 ft) concrete arched truss bridge (also known as a "bowstring bridge"), was constructed in 1916 to replace an earlier wooden bridge. As little boat traffic passed along this point of the Eramosa River, Wellington County engineer A. W. Connor and Italian-Canadian mason Charles Mattaini built the bridge low over the water. The bridge is named for the McQuillan family, which settled in Guelph in 1827, and is today also known as the Stone Road Bridge. It was named an Ontario Heritage Bridge in 2004. It is located along the township boundary between Guelph and Puslinch.
  The Eramosa River Bridge is a 15.24 metres (50.0 ft) reinforced concrete ridge frame bridge and was constructed in 1953 (as the Ospringe Bridge) to facilitate travel along Wellington Road 124 in Erin, Ontario, near the springs that feed the river. At the time of construction, the Ospringe Bridge was the fourth concrete ridge frame bridge built in Wellington County. It has since been renamed to, and is now the Eramosa River Bridge. A 2018 survey found the bridge to be in a state of advanced deterioration.
  The Lattice Covered Bridge was erected on 1 June 1992 by 400 members of the Timber Framers Guild. It is one of only two lattice bridges in Ontario, and was built based on a design originally drawn up in the 19th century. The bridge is 44 metres (144 ft) long.
