Hart Bridge over St. Johns River on SR-228

Project Overview

This rehabilitation of a major fixed-span steel truss bridge in Jacksonville, Florida, included structural repairs, lighting modification, and bridge painting. As the steel subcontractor, PCL removed and replaced 2,830 linear feet of expansion joint, replaced anchor bolts and sole plates, reinforced existing gusset plates, and repaired various plates and angles. The project team was also responsible for replacing approximately 9,200 deteriorated rivets/bolts in various locations along the truss. Approximately 6,245 square feet of catwalk grating and clip angles were replaced, and the existing bridge drains were modified in 136 locations.

The client’s main objective was to ensure that this major arterial bridge rehabilitation project reestablished the highest level of structural integrity possible. PCL worked with the client to provide an additional full inspection of the entire truss to identify numerous areas of major concern that resulted in a 300% increase in the number of repairs and rivet/bolt replacements. The project team completed these additional repairs within the original contract duration.

A portion of these additional repairs were significantly larger than the typical contract repair and would have traditionally been installed with a crane. The client requested the repairs be completed without a crane on the bridge deck to avoid damaging the existing structure, and PCL responded by using an innovative engineered winch system that did the job without a crane.
