Ada County history
Ada County company history timeline
Ada County was created on December 22, 1864.
Established December 22, 1864 with its county seat at Boise.
Boise became the capital of Idaho in 1865
During the 1880’s, the railroad made its way across Ada County, spurring additional settlements as construction camps and mail drops were established.
In 1901, Swan Falls Dam was completed on the Snake River to supply power to the mines in the Owyhee Mountains.
Located on Ustick Road between Five Mile Road and Cloverdale Road, Ustick Townsite was platted in 1907 and prospered due to its proximity to the Boise Valley Railway trolley system.
In 1912, the tracks were connected, providing a 66-mile trolley loop (Interurban Loop) around the Boise Valley.
In 1925, direct passenger train service came to Boise.
The first municipal airport was built in 1926 south of the Boise River on the present day Boise State University campus.
With the rise of the automobile there was less demand for a streetcar and the Interurban Loop stopped transporting passengers in 1928.
The airport quickly outgrew its riverfront location and moved to its current location in 1938.
In the mid-1960’s, construction on Interstate 84 began and plans for a greenbelt along the Boise River were initiated.
Ada County is a county in the southwestern part of the state of Idaho. Based on the 2010 census, the county had a population of 392,365, making it the most populous county in Idaho.
