County routes in California are special roads managed by the local counties. Think of them as important local roads that help people get around, especially in areas that aren't big cities. Even though the counties take care of these roads, the California Highway Patrol usually helps keep them safe.

Most county routes are two-lane roads. They are often found in country areas, but some also go through towns and cities. These roads are usually built to handle lots of cars and allow for normal driving speeds.

How County Routes Get Their Names

County routes in California are named with a letter followed by a number, like G2. The letter tells you which part of California the route is in:

• A, B, D are for Northern California.
• E, G, J are for Central California.
• N, R, S are for Southern California.

For example, a route named A1 would be in Northern California, while S1 would be in Southern California. Some counties, like Lake and San Bernardino, use only numbers for their routes.

Finding Your Way: Signs!

The signs for county routes can be different depending on the county. In San Diego County, you'll see signs for these routes often, just like on state highways. But in other counties, some county routes might not have many signs at all!

Usually, you'll find signs at the start and end of a county route, and where they meet other big roads. It's not common to see signs along the middle of the route. Most people refer to these roads by their street names, like "Angeles Forest Highway," instead of their route numbers.

History of County Routes

The system for marking county routes in California started in 1958. It's called the California Route Marker Program. Later, in 1967, this program became part of a bigger national program created by the National Association of Counties. This helped make road signs more consistent across the country.

Not all counties use the exact same signs or numbering systems. For example, Lake County has over 612 miles (985 km) of county roads, but they aren't listed here in the same way.
