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.
