US 50 over Tanners Creek Bridge

The new bridge construction featured modern safety and structural standards with two connector ramps; one as an on ramp from Main Street and Fourth Street, and the second as an off ramp to Bielby Road (Old SR 48). The new structure is a 5-span, continuous, composite, welded plate girder structure with spans of 125, 210, 210, 180, and 150 lft. The bridge was constructed with a minimum clear bridge width of 46 lft and a maximum clear roadway width of 74 lft, providing two 12 lft through lanes and a 12 lft auxiliary ramp lane diverging from the mainline; all with a 6 lft outside shoulder, and a minimum 4 lft median shoulder.

A new traffic signal was also placed at the intersection of Main Street and Fourth Street. The new bridge carries westbound traffic lanes on US 50 over Tanners Creek with approximately 0.46 mile of new roadway alignment. The roadway approach was constructed with MSE wall contained embankment and included both PCCP Concrete Pavement and QC/QA HMA Pavement. This project was constructed for the city of Lawrenceburg in conjunction with the Indiana Department of Transportation Seymour District. Construction costs were $12.5 million (Contract B-29261).

INDOT’s proposed modification to US 50 at Tanners Creek required the relocation of the floodgate that protects the city of Lawrenceburg from the Ohio River 500-year flood event. The project included the construction of an 84-foot by 12-foot by 5-foot rolling steel floodgate and new concrete flood wall/wing walls to replace the existing floodgate on US 50. Constant coordination was maintained throughout construction with the US Army Corps of Engineers (USACE). Work was performed for the City of Lawrenceburg. Construction costs were $1.47 million.
