<br />The stream is crossed hy three major hlgh~ay ~ridges, one
<br />railroad bridge and 14 street, county or prlvate bridgEls. Tabl02
<br />presents pertinent elevations for these structures and their relation-
<br />ship to the Intermediate Regional Flood. This information Is also
<br />presented graphically on the profiles wnile the focatlonsaM orien-
<br />tation of the roads is presented on the flooded area maps.
<br />Of the 18 bridges, the Intermediate Hegional Flood would
<br />overtops!x, IOrnorewould be flanked bywa-ter flowing arovnd them,
<br />and two are large enough to pass the flood. Nine bridge structure

<br />Not only are these bridges stressed by tile water flowing against them,
<br />but they tend to accumulate floatl~ debris whiCh furthor stresses
