Erie Harbor Piers 



Erie, Pennsylvania 



Date(s) Construction and Rehabilitation History 



1825- Construction of a 3,248-ft-long north pier (Figure 253) was completed 

 1900 during this time. The pier was a stone-filled timber crib structure 

 that ranged in width from 16.5 to 30 ft (Figure 254). 



1827- Construction of a 2,215-ft-long south pier (Figure 253) was completed 

 1903 during this period. This pier was also a stone-filled timber crib 

 structure that was 18 ft wide (Figure 254) . 



1903- Concrete and stone superstructures were installed on the north and 

 1909 south piers (Figure 254). The crest el of the south pier was +6.3 ft 

 Iwd, and the el of the north pier varied from section to section. 



1953- Rehabilitation and repair of portions of the north pier were per- 

 1956 formed. Portions of the pier were repaired by the installation of 

 steel sheetpiling, granular fill, and a new concrete cap (Fig- 

 ure 254, Sections A and D) . A total of 1,141 ft of the north pier 

 superstructure was rebuilt. 



1979 A disposal dike was constructed adjacent to the south pier 

 (Figure 253). 



1984 Portions of the north pier were repaired (Figure 253, Sections A, F, 

 and G) . These piers were encased in steel sheetpiling. The voids 

 between the sheetpiling and the existing timber cribs were granular 

 filled, and the structure was recapped with concrete (Figure 255). 

 The shoreward end of the north pier (Section A) was approximately 

 21 ft in width with a crest el of +7.3 ft Iwd. The lakeward portions 

 of the pier (Section F and G) were about 28 ft wide with an el of 

 +9.8 ft Iwd. 



1986 The piers are presently considered to be in good condition. An 



aerial photo of the Erie Harbor piers prior to the construction of 

 the disposal dike is shown in Figure 256.
