<br />o Is there a need for relief bridges? Should they or the <br />main bridge be larger? <br /> <br />o Are bridge abutments properly aligned with the flow and <br />located properly in regard to the stream <br />channel and flood plain? <br /> <br />o <br /> <br />Is the bridge crossing of <br />in a desirable location? <br />problems: <br /> <br />the stream and the floodplain <br />If the location presents <br /> <br />a. Can it be changed? <br /> <br />b. Can river training works, guide banks or relief <br />bridges serve to provide for an acceptable flow <br />pattern at the bridges? <br /> <br />o Is the hydraulic study adequate to provide the necessary <br />information for foundation design? <br /> <br />a. Are flow patterns complex? <br /> <br />b. Should a two-dimensional, water-surface profile <br />model be used for analysis? <br /> <br />c. Is the foundation design safe and cost effective? <br /> <br />d. Is a physical model study needed and warranted? <br /> <br />59 <br />
