A state highway in the United States is a numbered highway primarily administered by a state government. These are generally a mixture of primary and secondary roads, although some freeways double as state highways (for example, Route 128 in Massachusetts).
State highways also exist in other federal countries such as Mexico and Australia, and provinces of Canada maintain provincial highways.
Statehighway, and state route are terms that usually apply to numbered highways that are primarily administered and financed by a state government in countries that are divided into states.
A distinction is sometimes made between a statehighway - a road maintained by the state - and a state-numbered route - a road assigned a number by the state.
In the United States, a statehighway, state route, or state road (depending on the state) is a numbered highway primarily administered and financed by the state government.

Instead of terminating at Leggett, California StateHighway 1 was originally planned to follow the Pacific coast even farther north from Rockport to Ferndale.
