However, the procedures for designing culverts and bridges are significantly different due to the differing risks associated with the size of the structure. While it is recognized that any structure with a span over 6.096 m is technically not a culvert, for simplicity, all structures in this chapter will be referred to as culverts. The information in this chapter applies to both culvert and bridge size culverts. Structures spanning more than 6.096 m (20 ft.) along the center line of the roadway are considered bridges. Definitions (explanations of the terminology used in this chapter) follow: A culvert is defined in the Standard Specifications as any structure, whether of single- or multiple-span construction, with an interior width of 6.096 m (20 ft.) or less when the measurement is made horizontally along the center line of the roadway from face-to-face of abutments or sidewalls. Unique environments need to be thoroughly evaluated and all environmental requirements satisfied. Each location will usually have some unique character (floods, scour, surroundings, salt water, historic character, etc.). The history of the project site must always be evaluated and must be factored into each design. Engineering judgment will need to be used for most projects. It is not possible to provide guidance for all conditions so guidance is provided for the typical design. The designer has the ultimate responsibility to provide an efficient, safe design. As with any structural engineering design, alternate design methods are available. A list of available references needed to complete a culvert design is also provided. The information in this chapter is intended to be used as guidelines and minimum recommendations. It also provides guidance about the information to include in the contract documents, where to present the information, and details for cast-in-place culverts. This chapter presents the requirements for designing reinforced concrete culverts.
