Geiger Brothers has completed renovation of three steel truss bridges under contract to the Jackson County Engineer. The company removed, rehabilitated and then replaced these bridges after completing truss structural upgrades in its Jackson fabrication shop.
The bridges span Salt Lick Creek on Jackson Township Road 217 (Brohard Road) just west of U. S. Route 35, Symmes Creek on Jimes Emory Road (County Road 49) in Madison Township, and Four Mile Creek on County Road 11 (Four Mile Road) near Franklin Grange Road.

The Jackson County Board of Commissioners, upon recommendation of the Jackson County Engineer, awarded the contract for the rehabilitations. The Engineer noted the bridges were installed in the 1950s and 1960s. He stated this method of giving new life to older bridges saves funds and that the rehabilitation project will make them last another 50 or 60 years.
Geiger Brothers provided design services in addition to dismantling, removing, rehabilitating and replacing the bridges.
Geiger Brothers removed the existing bridge flooring, dismantled the structures, and then removed and cut each of the four- to six-ton trusses for transport. Structural upgrades were made in the Geiger Brothers Jackson fabrication shop, where welding personnel reinforced truss members and gusset plates and re-joined each truss. Once repaired, the bridge components were sandblasted and galvanized.
Each bridge was then reconstructed at the sites. Upon re-setting the trusses, construction personnel installed new stringers, floor beams and decking and then applied the asphalt paving to complete the work.
