Introduction: The originally proposed plan for the Morganza Floodway project included a separate control structure at its head located adjacent to the main-line levee of the Mississippi River., and a high-level crossing for Louisiana State Highway No. 30 and the Port Allen Branch Line at the Texas and Pacific Railroad from Morganza to Lacour. The locations at these features are indicated on plate 1. The crossing was to consist at a combined embankment which would extend into the floodway a short distance and connect with separate reinforced concrete trestles tar the highway and railroad. The trestles would be about 18,750 ft in length. Initial construction of the combined embankment was started 1n 1941 but construction was stopped in 1943 due to cessation or civil work as a result of the war. No work was performed on the trestles except for pile tests. During and following construction or the embankment, a few embankment and foundation failures occurred which indicated the need for further investigation of the stability of the embankment before it was brought to grade.
