This presentation describes the design and construction of the new Corpus Christi Harbor Bridge project which has recently been opened to the public. It includes a listing of the design and construction team members, the history of previous Corpus Christi Harbor Bridges and a historical review of the new bridge. Technical details regarding the large diameter drilled shafts for the main towers and driven prestressed precast concrete (PSPC) piles for the approach spans are elaborated. This includes the TxDOT geotechnical design requirements and foundation quality control measures regarding the 10’ diameter drilled shafts and the 24” square PSPC pile capacity estimation with load test verification. Statnamic load tests for the concrete piles, thermal integrity testing for shaft placement verification and PDA capacity and integrity verification measures for the concrete piles are discussed. A description of the soil conditions across the project site including deep soft soil and expansive soil areas and evaluation procedures.
