Bridges and culverts can
potentially alter the flow regimes of the river
thereby affecting water velocity, depth, depositional patterns and channel morphology. Theses changes in turn may increase the risk of flooding and erosion. Surface water quality could be affected by a number of factors during operations on site.
Will a bridge be safe?

now perform far better in service
