MAH-76-0.86 BRIDGE REHABILITATION (Mahoning County, Ohio)
This $15m bridge rehabilitation project entailed deck replacement and widening of the 2000’ long twin structures over Lake Milton. Two alternate designs, concrete and steel, were prepared. The more economical concrete design was constructed. 5’ deep PC wide flange I-beams were employed. Expansion provisions were made by providing intermediate and end expansion joints using strip seals. Existing steel H-pile bents were extended in the median. Abutments were rehabilitated by replacing back walls. Abutment breast walls were also partially/totally replaced. A MOT study to identify the various methods for maintaining traffic was prepared. A crossover scheme was used. The steel Alternate design included the rehabilitation of the fatigue-prone intermediate hinge connections in the existing girders. Salvaging the existing, new lines of steel girders were used to widen the deck in the median to accommodate two lanes of traffic for future deck replacements.



MOT-75-13.71/13.92 BRIDGE REHABILITATION/REPLACEMENT (Montgomery County, Ohio)
MOT-75-13.71/13.92 involves the rehabilitation of MOT-75-1371 over the Great Miami River and the replacement of MOT-75-1392 over North Bend Boulevard / Webster Street. MOT-75-1371 R is a 7-span structure carrying four lanes of traffic over the Great Miami River with diverging 2-lane ramps to I-75NB and SR 4 EB. MOT-75-1392 is a 3-span continuous steel beam structure with a reinforced concrete abutment on a spread foundation and cap and column piers which carries two lanes of SR 4 EB traffic over North Bend Boulevard Webster Street. Barr & Prevost is currently preparing rehabilitation/replacement recommendations for both bridges for
ODOT.


CUY-77-1143 PART OF CUY-77-11.11 BRIDGE REPLACEMENT (Cuyahoga County, Ohio)
Barr & Prevost provided all design related to the replacement of the existing 2-span bridge CUY-77-1143 carrying Grant Avenue over I-77. The revised scope of services called for a bridge design without piers, dictating a minimum face to face of abutment distance of 129.5’ to clear I-77 and meet lateral clearance requirements. To minimize superstructure depth and meet vertical clearances, a creative design solution was developed using short anchored end spans, which reduced bending and deflection in the main span and helped in controlling the depth.


FRA-71-4.31 BRIDGE REPLACEMENT/PROFILE IMPROVEMENT (Franklin County, Ohio)
This project involved a profile improvement and the replacement of a deficient structure on Young Road over Interstate Route 71 with a two-span continuous steel girder structure. The project length is approximately 0.51 mile. The new profile raised Young Road to improve minimum clearance over IR 71. MOT plans included a traffic detour and limited 30-day lane closure. Additional details included signing and marking plans, preparation of R/W plans, and utility relocation. Barr & Prevost received a consultant rating of 91% for services provided on this project.
