County: Mercer 
Municipality: Greenville Borough
State Route: N/A
Local Name: Ohl Street
Project Type: Bridge
MPMS Number: 1745
Proposed Construction Start: 2026
Last Updated: 03/06/2026

This is a project to remove the bridge that carries Ohl Street over the Shenango River in Greenville Borough, Mercer County.

The bridge is located approximately 1,200 feet east of the intersection between Ohl Street and Route 18.

Plans include the creation of a temporary causeway, removal of the bridge deck, trusses, and pier. The bridge abutments, or support walls, will remain in place. As part of the construction project, permanent protective safety barriers and signs will be installed on the east and west approaches. 

The existing Pratt through-truss bridge was built in 1908. It is rated in poor condition and was closed in 2009 due to deterioration. In 2025, the river under the bridge was closed to the public due to safety concerns. 

The bridge is owned by Mercer County. 

Section 4(f) of the U.S. Department of Transportation Act of 1966 requires transportation projects take into consideration the effects the project may have on public parks and recreational lands, wildlife and waterfowl refuges, and historic sites that are eligible for or listed on the National Register of Historic Places (NRHP). 

Three Section 4(f) resources are present in the project area: 

• Ohl Street Bridge – Classified as historic; removal of the bridge constitutes a Section 4(f) use of the bridge; conversations are ongoing with local historical societies about possible preservation of parts of the bridge. 

• Bessemer and Lake Erie Railroad Greenville Shops – Classified as a historic location; there will be no use of the property. 

• Upper Shenango River Water Trail – Designated water trail; currently closed in the area surrounding the bridge and will be reopened to boating at the conclusion of the project. 

The online plans display provides opportunity for the public to comment on how the proposed project may impact the activities, features, and attributes of the Section 4(f) properties.
