the aid of local and State road associations, chambers of commerce, automobile clubSj 

 postmasters, and private individuals in order to obtain adequate information. On 

 account of the absence of detailed records in many of the towns and counties extreme 

 accuracy is impossible. The data on mileage and revenues should therefore be con- 

 sidered as approximate only. Because of the large amount of correspondence neces- 

 sary to conduct the investigation, considerable delay in the issuance of the data has 

 been unavoidable. 



Bulletins already have been issued for the Middle Atlantic States, the New England 

 States, and the Southern States, respectively. These, together with this bulletin, 

 which contains data for the Central, Moimtain, and Pacific States, form a complete 

 series embracing all of the 48 States. A convenient reference summary of all of the 

 States also is issued coincident with this bulletin. 



ROAD ADMINISTRATION IN THE CENTRAL, MOUNTAIN, AND PACIFIC STATES. 



The, greater part of all road and bridge work in the States comprised in this group 

 is done under the supervision of coimty, township, or district authorities. There is, 

 however, an-increasing tendency toward State participation and management. Laws 

 have been enacted creating or designating State highway departments or commissions 

 in the States of California, Colorado, Idaho, Illinois, Iowa, Michigan, Minnesota, 

 Missoiu-i, Montana, New Mexico, North Dakota, Ohio, Oregon, South Dakota, Utah, 

 Washington,, and Wisconsin. Duties somewhat similar to those exercised by State 

 highway departments or commissions are imposed upon the State engineer in the 

 States of Kansas, Nebraska, Nevada, and Wyoming; and all the functions of a State 

 highway department or commission are exercised by the State engineer and the State 

 board of control in the State of Arizona. An outline of the system of road adminis- 

 tration in force in each State is given under the respective State headings. 



PUBUC ROAD REVENUES. 



The total revenue applied to roads and bridges in the Central, Mountain, and Pacific 

 States in the year 1914 amounted to $131,446,647.62, including State appropriations, 

 motor-vehicle registration and license fees, amounts derived from local taxation, and 

 expenditures from bond issues, both State and local. In 1904 the total revenue 

 applied to this purpose amounted to $36,794,586.67. The increase in 1914 as com- 

 pared with 1904 was, therefore, $94,652,060.95, or 257.24 per cent. Table 1 presents in 

 condensed form the information assembled concerning revenues for this group of 

 States for the year 1914, with comparative information for the year 1904.
