Tanglewood/Bayou Grande Bridge Replacement

This project consisted of the replacement of the existing Tanglewood Bridge servicing Bayou Grande Boulevard northeast over Tanglewood Canal in Pinellas County, FL. The 67-year-old bridge exceeded its expected service life and was experiencing ongoing deterioration. This bridge was posted for load restrictions due to its condition. As a result, the City of St. Petersburg slated this structure for replacement. Under KCA’s Transportation, Stormwater Management, and Bridge Inspection Contract with the City, KCA performed all structures, roadway, and drainage design for the project. Due to the bridge replacement taking place over navigable waters, environmental services and permitting efforts were completed in house, including seagrass surveys, U.S. Coast Guard (USCG) involvement, and public involvement. This bridge provides the only access to Tanglewood neighborhood. As a result, the bridge replacement included a phased construction sequence to maintain resident access and utility operation throughout all phases of construction. Innovative solutions were implemented to minimize noise and vibrations in this residential neighborhood.
