Menominee Harbor Piers 



Menominee, Michigan 



Date(s) Construction and Rehabilitation History 



1871- Construction of a 566-ft-long north pier (Figure 63, Sections A 

 1874 and B) and a 1 ,913-f t-long south pier (Figure 63, Sections E, F, A, 

 and B) were completed during this time. The piers were initially 

 constructed with woodpiling and stone. The pilings were installed 

 13 ft apart on the shoreward ends of the piers (Figure 64, Sec- 

 tions E, F, and A) and 17 ft apart on the lakeward ends of the struc- 

 tures (Figure 63, Section B) . 



1877- Extensions of the north and south piers by 596 ft and 613 ft, respec- 

 1879 tively, were completed (Figure 63, Section C) . The extensions con- 

 sisted of stone-filled timber crib structures (Figure 64, Section C) . 



1883- Construction of the heads of the north and south piers was completed 

 1884 (Figure 63, Section D) . The lakeward end of the north pier was 62 ft 

 long and was of stone-filled timber crib construction, while the 

 lakeward end of the south pier was 162 ft long and was of rubble- 

 mound construction (Figure 64, Section D) . 



1912 The shoreward 566-ft portion of the north pier was reconstructed, 



(Figure 63, Sections A and B) . Steel sheetpiling was installed that 

 resulted in pier widths ranging from 21 to 27 ft. The structures 

 were stone filled and capped with a concrete superstructure at an el 

 of +7.0 ft Iwd (Figure 64, Sections A and B) . Riprap toe protection 

 also was installed. 



1915 A 508-f t-long portion of the south pier (Figure 63, Sections A and B) 

 and a 596-f t-long portion of the north pier (Figure 63, Section C) was 

 reconstructed in a manner similar to that in 1912. Steel sheetpiling 

 was installed, filled with stone, and capped with a concrete super- 

 structure to an el of +7.0 ft Iwd (Figure 64, Sections A, B, and C) . 

 A 412-ft portion of the south pier had a 20~ft width (Section A) and 

 the remaining 96-f t portion a width of 25 ft (Section B) . the north 

 pier portion (596 ft long) had a width of 27 ft (Section C) . Riprap 

 toe protection also was placed on each side of both piers. 



1922 The 162-ft-long lakeward end of the south pier was modified (Fig- 

 ure 63, Section D) . A rock-filled concrete superstructure was built 

 on the existing rubble-mound pier. The superstructure had a crest el 

 of +7.1 ft Iwd with an 8-ft width (Figure 64, Section C) . 



1927 A 613-f t-long portion of the south pier (Figure 63, Section C) and 



the 62-f t-long lakeward end of the north pier (Figure 63, Section D) 

 were reconstructed. Steel sheetpiling was placed a width of 30.3 ft 

 apart on the south pier (Figure 64, Section C) . The voids were 

 filled with stone, and a concrete superstructure with a crest el of 

 +7.0 ft was installed. Riprap toe protection was also installed. 

 Steel sheetpiling was installed on each side of the north pier which
