Unit 4: How are highways designed?
G. Summary
The above information is an overview of the issues involved in highway design. Were you surprised that so many factors affect the design and so many decision need to be made?
The next time you travel down a highway, pay attention to all the features we talked about today, and think about all the people who worked together to create the highway. From the planners and elected officials who helped decide where the highway should go, to the engineers who performed the design, to the contractor who built the highway, and countless people along the way. A lot can be accomplished when people work together!
