Audubon Bridge and US 90 Bridge Updates

DBA’s work on the John James Audubon Bridge in Louisiana continues to move forward.  We have submitted our reports for the main river piers that include the recommended designs for post-grouted drilled shafts.  Test shaft construction is scheduled for late August or early September for an Osterberg Cell (O-Cell) load test.

Driving of indicator piles has begun at the US 90 Bridge from Biloxi to Ocean Springs, Mississippi.  A program of 21 indicator piles and 6 load tests (4 axial and 2 lateral) will be used to develop pile capacities and driving criteria for the project.  Eustis Engineering, Inc. is monitoring all indicator and test piles using the Pile Driving Analyzer (PDA).  The load tests will be performed using the Statnamic device in late August.
