The City of Treasure Island, Florida (near Tampa) will be spending around $100k to repair approach embankments to the Isle of Capri and Isle of Palms bridges.
…due to the degradation of seawalls and seals at the bridges, the approaches have “voids” under the road bed. The city recently spent $11,820 for a ground penetrating radar evaluation by Infrastructure Preservation Corp. to determine the severity of the problem. IPC identified various locations at each bridge where voids required filling. The filling will be accomplished using a pressure grouting or a flowable sand fill.
