Overview
The I-64 Sherman-Minton Bridge Design-Build project consists of performing major rehabilitation work to the more than 60-year-old Ohio River crossing. Following the discovery of severe deterioration during a routine inspection in 2015, the bridge was closed to traffic until repairs could be completed. The closure prompted an immediate study and the development of preliminary plans for comprehensive rehabilitation.
Process
Working alongside the Kokosing Design-Build Team, DLZ Kentucky developed rehabilitation plans for the approach structures on both the Indiana and Kentucky sides of the river. The overall rehabilitation scope addressed the main and approach spans, including replacement of main-span arch hangers; concrete deck overlays and replacement; replacement of deck joints with specially designed link slabs where feasible; replacement of rocker and fixed bearings; repair or replacement of deteriorated superstructure components; substructure repairs; and painting of steel superstructures.
In collaboration with Jacobs Engineering, DLZ also developed a maintenance of traffic plan supported by modeling of traffic volumes and flow patterns through each construction phase. DLZ managed utility and railroad coordination, along with public information and involvement efforts.
DLZ’s inspection services covered all approach structures on both sides of the river. These inspections documented existing conditions and evaluated and quantified the repairs proposed by general contractor Kokosing Construction Company, Inc., and designer of record Jacobs Engineering Group, Inc.
DLZ inspection services included the following:
Main Steel Tied-Arch Spans over the Ohio River, Spans 1 & 2 (INDOT Str. No. I64-123-04691 D)
