1957 Construction of a 938-ft-long east pier and a 530-ft-long west pier 

 was completed at the site (Figure 15) . The shoreward 370 ft and 

 372 ft of the west and east piers, respectively (Figures 15 and 16, 

 Section D) , were constructed with woodpillng and filled with stone. 

 Steel sheetpiling was installed also on the channel side at an el of 

 +8 ft Iwd. The remaining 160 ft of the west pier, and the next 

 286 ft of the east pier (Figures 15 and 16, Sections B and C) were 

 constructed of woodpillng with sand and stone fill. Steel sheet- 

 piling was installed on each side of the structure at a +8 ft el Iwd. 

 Stone was grouted in place to cap the structure. The west pier was 

 15 ft wide, and the east pier ranged from 17 to 45 ft in width. The 

 next 100 ft of the east pier was constructed of steel sheetpiling 

 with sand and rock fill (Figures 15 and 16, Section E) . This struc- 

 ture was 24 ft wide with a crest el of +8 ft Iwd. The outer 180 ft 

 of the east pier was a cellular sheet-pile structure (Figures 15 

 and 16, Section F) . The cells were filled with dredged sand or 

 gravel and capped with 2 ft of rocks filled with grout. The diameter 

 of the cells was 30.55 ft, and the crest el was +8 ft Iwd. Rock 

 berms were placed at the toe of the structure on both sides.
