About ITDIdaho Transportation BoardExecutive TeamContact InformationMission OverviewITD Org. ChartAeronauticsHighways
Idaho's transportation system is comprised of a statewide
network of more than 60,000 miles of road, about 4,000 bridges,
1,900 miles of rail lines, 125 public airports, and the Port of
Lewiston. Of these, the transportation department has
jurisdictional responsibility for almost 5,000 miles of highway
(or 12,000 lane miles), more than 1,700 bridges, and 30
recreational and emergency airstrips. Also included on the State
Highway System are 30 rest areas and 10 fixed ports of entry.
The transportation department also oversees federal grants to
12 rural and urban public transportation systems, provides state
rail planning and rail-project development, and supports bicycle
and pedestrian planning and projects.
highway system is heavily used
The state is responsible for nearly 5,000 miles of roadway
miles in Idaho, just eight percent of all roadway miles in Idaho.
However, the state highway system accounts for 54 percent of the
state's vehicle miles of travel (VMT). While the interstate
system accounts for just 12 percent of the total state highway
system mileage, 41 percent of VMT is on the interstates. From
1984 to 1998, VMT on the state highway system has increased more
than 63 percent.
provides an attractive alternative
In a largely rural state like Idaho, air travel is an
attractive alternative for business meetings, commercial
carriers, emergency services, recreational access and individual
trips. The Division of Aeronautics provides aid to all 69 city
and county airports and maintains 30 state-operated recreational
and emergency airstrips.
More than 4,000 Federal Aviation Administration
Over 2,500 registered aircraft.
125 public airports, including seven primary and
commercial airports; and 30 state-owned airports and airstrips.
More than 1 million visitors annually who arrive via
commercial airlines and general aviation aircraft.
transportation available to the majority of Idahoans
Public transportation service is available to 75 percent of
the state's population.
Three systems serve the state's largest cities with
populations of 50,000 or more:
Boise Urban Stages (BUS).
Pocatello Regional Transit (PRT).
Targee Regional Public Transit Authority in Bonneville
County (subcontracts to CART). Nine small-city and rural transit systems serve populations
North Idaho Community Express in Coeur d'Alene (NICE)
serving Kootenai, Bonner, Boundary and Shoshone counties.
Trans IV serving Twin Falls and Jerome counties.
Moscow-Latah County Public Transit (MPT) serving Latah,
Clearwater, Lewis and Idaho counties.
Ketchum-Sun Valley Transit Authority (KART).
Treasure Valley Transit serving Canyon County.
Region Public Transportation in Lewiston (RPT).
Valley Vista Care serving St. Maries and Benewah
Pocatello Regional Transit serving Bingham, Bannock and
CART serving Lemhi, Jefferson, Teton, Madison, Custer,
Butte, and Fremont counties.
In addition to these agencies, there are nearly 70
organizations providing public transportation to the elderly and
disabled across the state using lift-equipped vehicles purchased
with federal funds.
In the last several years, voters in Idaho created two
Regional Public Transportation Authorities (RPTA). The Targee
Regional Public Transit Authority oversees public transportation
in Bonneville County and the Treasure Valley RPTA operates in
Canyon and Ada counties.
railroad system connects Idaho with nation, Canada and Mexico
The 1,887 miles of railroad lines in Idaho include main lines,
secondary lines, branch lines and short lines. The state is
served by the Union Pacific and the Burlington Northern Santa Fe
railroads, providing connections to the United States, Canada and
Mexico and six short line railroads, which act as feeders to the
large rail carriers.
The transportation department neither owns nor
operates rail lines. The role of the state rail program is to assist in the
preservation of essential rail lines through planning and administering the
federal Local Rail Freight Assistance Program and other federal funds that could
