The Monongahela (Mon) River Bridge is part of the 24-mile long Mon/Fayette Expressway. The expressway will be a limited access highway with toll collection facilities within the limits of the facility. The expressway will be four lanes with a variable width median. Each roadway of the Mon River Bridge will carry 4 lanes of traffic with 12-ft. inside and outside shoulders.

The objective of the Mon River Bridge Project is to refine the preliminary designs presented in the Draft and Final Environmental Impact Statements (FEIS) and prepare final construction plans, specifications and cost estimates. The length of the project is approximately 2,100 feet and entirely on structure. The project has been organized into three phases: preliminary engineering, final design and post design services. Design duration is estimated to be 60 months, 36 months for preliminary engineering, and 24 months for final design. The duration of post design services has not yet been determined. A bridge type study was performed to evaluate several alternatives for efficiency and aesthetics. These bridges included cable-stayed, tied arch, deck truss and through truss options.

Several bridge types are under consideration during preliminary engineering resulting in the need for 3D conceptual visualizations for comparing alternatives. The arch bridge renderings are shown above.
