California 138 follows the proposed alignment of the Metropolitan Bypass, a freeway that would arc to the southeast around the urbanized parts of the Los Angeles Basin, providing a freeway connection between Interstate 5, California 14, and Interstate 15.
California 138 crosses Interstate 15, and it becomes part of the Rim of the World Highway as it approaches Crestline (where it ends at its junction with California 18).
Similar to the California 99 merge, the objective of the auto/truck bypass is to allow slower traffic to merge with slower traffic first and faster traffic to merge with faster traffic.
