American Society of Highway Engineers (ASHE) Central Ohio Section
The first-ever Public/Private Partnership (P3) project for ODOT involved the design, construction and long-term maintenance of a new 16 mile, four lane divided, limited-access highway around the City of Portsmouth, Ohio, bypassing approximately twenty-six miles of US-52 and US-23. The highway is designated as State Route 823 (S.R. 823), the Southern Ohio Veterans Memorial Highway.
The project included construction of 5 new interchanges and 23 new bridges. The project delivery method was Design-Build-Finance-Operate-Maintain (DBFOM). Design of the project started on January 5, 2015 and the highway opened to traffic on December 14, 2018.
This roadway completes the Appalachian Highway System in Ohio, serving as a bypass around the City of Portsmouth, where congestion was a growing problem.
Benefits of the additional route include:
Economic development is also a large part of the project’s purpose. In 1965, the US Congress created the Appalachian Development Highway System (ADHS) expressly to provide growth opportunities for the Appalachia residents. The region is absent of available locations for new business sites due to the hilly terrain and brownfields along the US-23 and US-52 corridors. This new highway, along with the three interior interchanges, opens up land previously inaccessible and under-developed.
During the bidding and design phase of the project, all parties worked closely to develop the complex design and construction schedule. The project was broken down into four major segments, and then approximately 50 constructible buildable units (BUs).
ms consultants, as lead designer, performed the majority of design work, as well as managing the deliverables for each BU.
Coordination and communication between organizations was critical for the timely completion of this project. In addition to ODOT, the Portsmouth Gateway Group, and the consultant teams, other entities were also involved:
When construction commenced in June 2015, the coordination effort for construction personnel, equipment, and material deliveries was massive.
Along the entire sixteen mile alignment, there were significant cuts and fills up to two hundred feet. The majority of the cuts included rock that had to be blasted and required rock-fall analyses and catchment designs for several different rock types.
Construction of the Southern Ohio Veterans Memorial Highway project included:
