The Project
This $7.1M locally-administered project rehabilitated the Triple Decker Bridge (built in 1948), to extend its service life. The project also features installation of an advanced height detection system that automatically alerts drivers when their vehicles exceed the clearance limit of the overhead structure. RK&K provided construction management, engineering, and inspection; environmental permit and commitment compliance; review and analysis of change orders; and project controls/CPM scheduling for this project, including calculating production rates and activity durations for contract work; developing the CPM schedule following the sequence of construction and calculating the project duration; and producing report summarizing findings.
The bridge consists of three levels:
The top-level features Route 13 (Military Highway), which crosses over both the Norfolk Southern Railway and a Route 166 (Bainbridge Boulevard) exit ramp. This section is constructed with a combination of two simple and five continuous concrete T-beam spans.
The middle level accommodates both the exit ramp to Bainbridge Boulevard and the Norfolk Southern Railway’s double tracks. The exit ramp portion utilizes a uniquely designed steel span, characterized by its severe angle and specialized support system.
The bottom level supports Bainbridge Boulevard through a pile-supported roadway design. Due to its low elevation, this underpass required an on-site pumping station.
Project elements included bridge jacking and blocking, bridge deck removal and replacement, structural steel repairs, structure excavation, bearing replacements, Type A and B crack repairs, bridge substructure thermal spray coating.
Extensive coordination was required with the City of Chesapeake and Norfolk Southern to ensure the project was constructed in accordance with contract plans and specifications, along with Norfolk Southern’s special provisions for protection of railway interests as repairs were performed over and adjacent to the railroad.
