IDAHO, « 
Idaho has a land area of 53.354 square miles, and a total road mileage of 24.396, of 
which 679 miles, or 2.75 per cent, were surfaced at the close of 1914. 
The State highway co m mi ssion consists of the secretary of state, who is ex officio 
a member and secretary, and two other members appointed by the governor for terms 
of three years. The commission appoints a State highway engineer, who is the execu- 
tive officer of the com mi ssion and may be removed by it. The State highway com- 
mission, acting through its executive officer, has general powers and jurisdiction over 
the laying out. constructing, improving, and maintaining of a system of State high- 
ways and bridges and the expenditure of State highway funds. The commission is 
authorized to appoint such assistant engineers and other assistants as may be necessary 
and also to advise, assist, and cooperate with local road officials in all matters per- 
taining to highway and bridge construction and maintenance. 
A system of State highways, to consist of main trunk lines connecting the larger 
centers of population, was to be selected by the State highway commission and plans 
prepared therefor. All highways constructed by the State or by the aid of the State 
are State highways and shall be maintained at the sole expense of the State. Where 
highways are built by the State in cooperation with a county or a highway district 
or a good-road district in any county, the county must pay. if the cooperation is with 
a county, not less than two-thirds of the cost, and the district must pay. if the coop- 
eration is with a district, not less than one-half the cost, if the taxable valuation of 
the district is $1,000,000 and less, and not less than two-thirds of the cost if the tax- 
able valuation of the district is more than $1,000,000. State bonds are authorized to 
pay a portion of the cost of constructing the system of State highways. A State 
highway fund is created for a like purpose. 
The board of county commissioners in each county is vested with jurisdiction in 
all matters pertaining to roads and bridges therein. Boards of county commissioners 
may divide their respective counties into suitable and convenient road districts and 
appoint one road overseer for each district. The road overseers are subject to removal 
by the board of county commissioners. A board of county commissioners may appoint 
a road supervisor for the county who shall have i mm ediate control of all road and 
bridge work in the county under the board of county commissioners.
