  • Culverts - Types of Structures

    Credits: 4 PDH

    PDH Course Description:

    This course provides a summary on the principles of construction and design of various types of culvert structures. A wide variety of culvert structures are currently in use as stream crossings, underpasses, and other highway and railroad applications.  Although modern culverts are made primarily from reinforced concrete, corrugated metal, and, more recently, solid-wall, profile-wall, and reinforced plastic, some culverts constructed with stone masonry, terracotta, or timber still exist. The emphasis of this course is primarily on modern culvert construction.
