California Mileage Markers

To make things easier for you in areas where landmarks and signposts are not available, we often list the nearest highway mileage marker. This is how you read them:

These markers are found on state highways. Look for them in the grass at the side of the road.

The letters indicate the county and the numbers indicate the mile it marks.

Unlike mileage markers in some other states, California markers are numbered in the same sequence going in both directions. The marker just opposite this one on the other side of the road is also marked 37.54. The markers are not at regular intervals and are sometimes extremely close together for no apparent reason.
