Local government leaders quite often contend that upgraded highways ar
e important to their communities' economic development potential. This
article examines the degree to which investments in high-capacity hig
hways are likely to influence business location decisions, given the m
ature nature of the interurban highway system in the United States. Th
e authors examine the conceptual relationship between highway investme
nts and facility location, review literature on location factors, and
present the findings of surveys of business facility managers in Misso
uri and Iowa. They conclude that access to a highway generally has bec
ome less of a factor in location decisions and discuss the implication
s of this conclusion for state-level highway investment policy.
