Ottawa County, OhioTo address a structurally deficient bridge, the Ohio Department of Transportation (ODOT) District 2 undertook the replacement of the Billman Road structure over Packer Creek, located off State Route 163 in Clay Township, Ottawa County. The original 22-foot cast-in-place concrete slab bridge was replaced with a longer-span design to meet current standards and accommodate the site’s complex constraints. The project improved structural capacity, enhanced traffic operations near a busy intersection, and ensured access for adjacent property owners and critical infrastructure.
The new bridge features a 37′-4″ single-span prestressed concrete box beam superstructure with a composite deck supported by semi-integral abutments on deep pile foundations. A significant challenge involved maintaining operation of a privately owned pump station, which was attached to an existing wingwall and included outlet works penetrating the same structure. To preserve the system during and after construction, the existing abutments and wingwalls were retained as scour protection, and custom guardrail anchorages were developed to maintain pump access.
Our team provided consulting services, including roadway, traffic, hydraulic, and structural bridge design, as well as environmental permitting. We redesigned the south approach to account for the deeper superstructure and its proximity—25 feet—from SR 163. This included realigning geometry to meet ODOT standards and relocating an existing field drive within the guardrail length in coordination with ODOT and the private landowner. The improved structure incorporated a flared approach and slab to enhance safety at the stop-controlled intersection. The project was completed three months ahead of ODOT’s design schedule, offering greater flexibility for bidding and construction.
