ATKINSONState Higliway Engineer of Louisiana 15 DRAINAGE struclui-fs like many other IVatures ofliighway eonstnictiiiii require the considerationof many factors in determining the type and characterof construction adaptable to any particular location,or in determining a uniform standard or design to beused throughout any parlicidar proposed liiglnvay pro-ject. Inasmuch as road construction together withdrainage structures ai-e more or less prolilems to be. W. E. ATKINSON solved by every state or highway commission to meetlocal conditions, I shall not attempt to set forth anyrules or plans governing the or construction of alldrainage structures, Imt merely present to .you some ofthe general nietlnKls, factors and policies governing theconstruction of such drainage structures in Louisiana,under the supervision of its highway department. In determining the length of bridges and spans l>e-tween bents and piers and the size of culverts, consid-eration is given to the maximum rainfall, amount ofrun off, average slope of groimd of drainage area, seep-age, etc., as included in the same factors governingsimilar structures under railroad construction. Afterdetenmduing the required opening for waterway, thefactor governing the required strength or carryingpower of the structure is delerinini^d, so far as it ispossible, upon the maximum load the structnre is like-ly to be subjected during its bonded Ifie.
