Kwakuhlelwe ukuba kuqhekezwe iqhwa kusukela eNorth Center Street Bridge kuze kube semlonyeni womfula, lapho ugelezela khona eSaginaw Bay - ibanga elingamamitha angaba ngu - 900. Phakathi nobusika obunzima bonyaka odlule kwasetshenziswa iziqhumane ukuze kuqhekezwe iqhwa lomfula ngokokuqala ngqá kusukela ekuqaleni kuka-2001. Ubukhulu beqhwa ngo-2014 babuwu- 24 inches, futhi iziphathimandla zithi kulo nyaka iqhwa selifinyelele kakade ku-23 inches. I - Huron Tribune yabika ukuthi izikhulu ziye zaxwayisa izakhamuzi ukuthi lapho umsebenzi usuphelile ngoLwesine, iqhwa lomfula ngeke libe liphephile kunoma yiluphi uhlobo lokusetshenziswa - ikakhulukazi izimoto.

Kwakungokokuqala kusukela ngo - 2001 ukuthi iziphathimandla ziphoqeleke ukuba zisebenzise lesi sinyathelo.  <response>: Ubusika obunzima buye benza iziphathimandla zasemzaneni waseSebwaing, eMichigan, ukuba zisebenzise iziqhumane ukuze zisuse iqhwa lomfula eliyingozi. Uma uba mkhulu kakhulu, iqhwa lomfula lingabangela izikhukhula. Ifinyelele ku-24 inches obukhulu ngo-2014, futhi njengamanje ingama-23 inches obukhulu. Ngaphambi konyaka odlule iziqhumane zazingakasetshenziswa kusukela ngo-2001. I-Army Corp of Engineers yajoyina izinhlaka ezahlukahlukene zombuso nezasekhaya ezabizelwa ukubhekana nale nkinga. Iziphathimandla zendawo zixwayise ngokuthi ngemuva kwalomsebenzi umfula oyiqhwa ngeke uphephe kunoma yiluphi uhlobo lokusetshenziswa - ikakhulukazi izimoto. Isiphepho sakamuva sasebusika sibangela umonakalo kusukela eTexas kuya eNew England, futhi isimemezelo sesimo esiphuthumayo simenyezelwe eKentucky.
