164 ft long, 54 in. diam prestressed concrete cylinder piles, precast pile bent caps, and precast prestressed deck units spanning 60 ft, weighing about 156 tons each, for construction of 3 mi long 60 ft wide bridge, were transported on barges from casting yard at Mandeville, La; most of bridge length is made up of two 6700 ft long concrete trestles; three spans, 123, 154, and 123 ft long, are of continuous welded steel plate girders; two 900 ft long sections of trestle are on 4% grade.
