Why is this important?
Transportation is the basic system providing mobility
to sustain social, economic, and recreational activities
in Tuolumne County. Properly developed, balanced
transportation systems result in effective mobility and
safe living conditions.
What is the measure?
We surveyed the basic modes of transportation—roads,
rail, and air.
How are we doing?
Tuolumne County features a fixed-route public transit
system, dial-a-ride transit system, pedestrian and bicycle
facilities, a working railroad, two public-use airports, and
a network of county roads and state highways. We have
no public transportation in or out of the county.
The condition of our local roads is projected to
decline. We have approximately 611 miles in our
road maintenance system. Roads built to serve new
development are not accepted into this maintenance
system. New roads are maintained by County Service
Areas, homeowners associations, or private property
Four state highways provide access to and through the
county. We have no designated bike lanes on the county
Tuolumne County is served by the Sierra Railroad, which
operates freight service between Oakdale in Stanislaus
County and Standard in Tuolumne County. It includes
49 miles of track and has operated since 1897.
General aviation needs in Tuolumne County are met by
two county-owned and operated airports. The Columbia
Airport (which has an historic grass runway) is located
in the community of Columbia, and the Pine Mountain
Lake Airport is located in the Groveland area. During
fire season, the Columbia Airport is also host to the
California Department of Forestry and Fire Protection
Columbia Air Attack Base.
