Credits: 4
Lecture Hours: 4
Lab Hours: 0
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
This course will introduce the student to highway design. Topics will include an overview of the highway development process, design criteria and standards, horizontal alignments, vertical alignments, cross-sections, earthwork, construction details, specifications and estimates of quantities. A final highway design project will be completed.
