Replacing aging, deteriorated infrastructure often requires road closures and traffic detours which impose
inconvenience and delay on commerce and members of the motoring public. Accelerated bridge construction
techniques often use precast members to reduce the duration of construction and the resultant disruption to traffic
patterns.
This project considered various technical, safety, and economic challenges in the design and construction of a full-width precast concrete slab with a centerline crown. Torque verified leveling screws compensated for girder, deck
panel prefabrication tolerances, and dead load deflections. In addition, the uniform-depth deck slab was cast by
conventional prestressing fabricators. The method to lift and transport the slabs was considered to prevent damage.
Accelerated bridge construction is less expensive and bridge work can be c
