TRU-TR123 BRIDGE

Euthenics provided project management, survey and basemapping, roadway and bridge design, hydraulic analysis, utility coordination, maintenance-of-traffic and detour planning, and final construction plans for ODOT PID 119203, replacement of the Barclay Messerly Road (C.R. 123) bridge over Eagle Creek in Braceville Township, Trumbull County, Ohio. The existing structure was a narrow one-lane steel pony-truss bridge with substandard vertical geometry. The replacement is an 88-foot single-span prestressed concrete box-beam bridge with six adjacent CB33x48 beams, a 6-inch composite reinforced-concrete deck, 24-foot face-to-face bridge width, no skew, a 1-inch monolithic wearing surface, and reinforced-concrete semi-integral abutments supported on piles. The bridge and approaches were designed to provide two 9-foot lanes and 3-foot shoulders while limiting grading and permanent work to the existing right-of-way. Euthenics developed a performance-based roadway profile to improve the design speed from less than 15 mph to a practical low-volume-road profile while balancing hydraulic opening, structure depth, approach grading, and nearby fiber-optic and 18-inch storm-sewer facilities. Hydraulic analysis documented improved headwater and upstream water-surface elevations and supported the project's no-rise certification. Scour protection includes 2-foot rock channel protection and the existing stone abutments cut down and left in place. Utility coordination addressed fiber optic, storm sewer, electric, and water facilities. Euthenics prepared detour plans for the full roadway and bridge closure and submitted final plans.
