State Transportation Services and Infrastructure

Roadways

Idaho’s road network comprises approximately 12,000 miles of state highways, 3,000 miles of interstate highways, and numerous local roads. The Idaho Transportation Department (ITD) oversees the maintenance and development of these roads, ensuring connectivity across urban and rural areas.

Public Transit

Public transportation options in Idaho are limited, primarily serving urban areas. The Valley Regional Transit in the Boise metropolitan area and the Pocatello Regional Transit provide bus services to residents. However, rural communities often rely on personal vehicles due to the scarcity of public transit options.

Railroads

Rail transportation in Idaho is primarily freight-based, with limited passenger services. The Union Pacific Railroad operates extensive freight lines through the state, facilitating the movement of goods to and from Idaho.

Airports

Idaho is served by several public airports, with the Boise Airport being the busiest, offering domestic and limited international flights. Other notable airports include the Idaho Falls Regional Airport and the Pocatello Regional Airport.

State Laws, Regulations, and Policies

The Idaho Transportation Board, authorized by Section 40-312 of the Idaho Code, is responsible for prescribing and enforcing rules and regulations affecting state highways. The Board also determines which highways or sections of highways shall be part of the state highway system. (law.cornell.edu)
