Jefferson Boulevard over St. Joseph River Bridge

Rehabilitation included removing the deteriorated spandrel walls, patching the arch ring, and rebuilding the bridge with a concrete pavement and drainage system to reduce future deterioration. Structural strengthening was added inside the arch to resolve some design deficiencies in the original bridge, which had led to sagging of two of the spans. Coordination and permitting with numerous historical agencies and research of historic records resulted in the recreation of many features and details that had been lost or covered up over the years. This project won an American Concrete Institute award for Outstanding Achievement in Concrete Design.
