Abstract
Geometric highway design deals with the dimension of those highway features such as alignment, grades, widths, sight distance, clearances and slopes as distinguished from structural design which deals with such features as thickness, composition of materials and load carrying capacity. There standards are intended to be applied as general design controls regardless of the system of which the highway is a part. The use of more liberal values than the indicated minimum values herein is recommended where conditions are favorable and costs are not excessive.
