ABSTRACT 
Historically, aerial surveys and highways were 
not joined on an effective and mutually complementing 
and augmenting basis for almost fifty years after 
their separate and distinct motivations in the 1890's 
on a concerted-effort basis. This paper contains the 
salient historical data regarding aerial surveys and 
highways in relation to each other. 
Principles and procedures are presented in some 
detail by stages of highway engineering to show how 
intricately, in the United States, aerial surveys and 
highway engineering are interwoven, and to point to 
many of their joint ramifications. Undoubtedly there 
are others. Many of such principles and procedures 
are employed in other countries. 
The role of aerial surveys in highway engineer- 
ing is intrinsically a part of the nature of aerial 
photographs, and surveys for, and design of, highways. 
Detailed chronology of the application of aerial sur- 
veys in highway engineering are comprehensively given

for the preliminary engineering stages and briefly for 
construction and subsequent stages. Uses of electronic 
computations in highway engineering and procurement of 
aerial photographs and photogrammetrically compiled 
maps by contract are presented. 
Practices and procedures vary from user to user, 
but the importance to, and influence on, each other-- 
aerial surveys and highways--will continue to grow.
