Fundamental to establishing bridge geometry and the resulting geometry and dimensions of bridges is the ability to work with roadway geometry provided by highway designers.  Terminology used in roadway geometry is discussed.  The three primary aspects of roadway geometry (horizontal alignment, vertical profile, and cross section super elevations) are presented in this course.  Stationing along horizontal alignments is also defined.  Mathematical formulae and graphical representations are presented to define these three primary aspects, along with worked example problems.

In this course you will:

• Identify general impacts of roadway geometry on bridge layout
• Identify terminology used in roadway geometry as it relates to bridges
• Describe aspects of roadway horizontal alignment, vertical profile, and cross section superelevation
• Evaluate mathematically the elevations and superelevations by station along an alignment
