Many times, these bear the same number as the parent highway, with a letter suffix. Some state highway spurs and loops from US highways have designations that are drawn from the parent US Highway designation. As higher-level roads replaced sections of some routes, those sections sometimes had their designation revoked. This led to some highways being fragmented, missing one or more sections in the middle of the road. There are also a few unrelated highways that are designated in completely different parts of the state with the same number.
