Te temperature determines the type of materials that are used some tend to shrink and expand when the weather changes. Other weather conditions like wind precipitation should also be considered. 9.10.Four famous bridges that are located in canada are the capilano bridge in vancouver,The confederation bridge connecting P.E.I. and New Brunswick, the Quebec bridge in Quebec, and the Rainbow bridge in Niagara falls.
