The $18.5 million project is also still on budget, Gruner said.
Local, state and federal agencies are funding the project, with the Ohio Department of Transportation covering 95% through the Local Major Bridge Program.
The Third Street bridge, which is also known as the Peace Bridge, was built in 1904. In 1949, it underwent a major rehabilitation, with emergency repairs needed in 2010 and 2011.
The replacement project included a new foundation for the bridge. It is also being widened from four to five lanes with 10-feet-wide sidewalks on the north side and 12-feet-wide paths on the other.
