Hamilton County Park District Sharon Woods Kreis Dam and Bridge Repair
Rusting at the bottom of corrugated metal arches was causing the top of the concrete piers extending above the dam to deteriorate and threatening the stability of the structure. The bridge was essential to the park as the main access to the golf course and a vital section of the scenic trail loop extensively used by walkers and joggers around the lake.
Solution
Remove the earth backfill over the metal arches and replace it with reinforced concrete, using the existing metal arches as forms for the new concrete. Doing this changes the bridge to a reinforced concrete arch structure, eliminating the need for the metal arches.
Details
Final cost was $415,600 ($14,000 under the estimate). The bridge was out of service for three months during the winter while under construction. This is two months and $300,000 less than a new bridge.
