What negative aspects might you encounter when Building Bridges?
I suppose, what you mean by negative aspects are the obstruction when doing such activitiesIn this case, i can mention several things: 1Presence of water in constructing foundations - that's why you need to put sheet piles to prevent water going inside the area of foundation 2Accessibility - the access in constructing the girders are very limited that's why you need to put pre cast girders with help of crane mounted on a barge 3Safety hazard 4Hydrologic study - the flowing river or tide varies from time to time so you need to have a good timing in constructing bridges 5Environmental problems - some areas preserve the natural habitat of their bodies of water so you need to acquire special permits prior to construction of bridge
