Naming
The expressway is officially referred to as the Chūgoku-Ōdan Expressway Onomichi Matsue Route. The Chūgoku-Ōdan Expressway Onomichi Matsue Route is the official designation for the Sanyō Expressway between Onomichi Interchange and Hiroshima Junction, the Onomichi Expressway between Onomichi Junction and Miyoshi-Higashi Junction, and the Matsue Expressway between Miyoshi-Higashi Junction and Matsue Interchange (concurrent with the Chūgoku-Ōdan Expressway Onomichi Matsue Route).

The route originates from its junction with the Sanyō Expressway and extends northward. At its northern terminus it connects to the Chūgoku Expressway. The entire route is toll-free with the exception of the short (0.9 km) section between Onomichi Junction and Onomichi Toll Gate.
