Broad Avenue Bridge Replacement over Flint River

Project Overview

This project included demolishing an existing condemned concrete spandrel deck arch bridge and replacing it with a cast-in-place segmental box girder bridge. The new bridge will be four spans, with the longest span at 320 feet. Three of the spans will be constructed by cast-in-place balanced cantilever method with form travelers. The fourth span will be box girder bridge construction on falsework. The piers with large architectural brick inlays sit atop 66-inch and 72-inch drilled caissons.

By using accelerated bridge construction (ABC) methods such as balanced cantilever, the project team avoided impacts to multiple endangered species while adhering to strict environmental regulations and expediting the overall project construction schedule. The original project design required masonry stone facing at each pier. PCL proposed and implemented an alternate stone face form liner that provided a realistic masonry stone look. This alternative provided the owner with several benefits, including eliminating environmental risk (installation of masonry stone would have impacted the mussel breeding season), reducing original masonry duration, and removing masonry stone face installation from the critical path.
