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).

Overview

The first section of the expressway was opened in 2010. The final section of the expressway (18.4 km between Kisa Interchange and Sera Interchange) was opened on March 22, 2015. 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.

The route is 2 lanes for its entire length, with some overtaking areas. The speed limit is 70 km/h.

gollark: It looks like it somehow incurs a "bitmap heap scan" and "nested loop" but I have no clue why.
gollark: I don't understand why including `ts_headline(pageText, query, 'MaxFragments=3,MaxWords=60')` suddenly makes Postgres decide to operate about 100 times slower on this.
gollark: You lose ubqoral then.
gollark: I don't understand why, but adding a snippet of the page text to each thing appears to make the search query about 100 times slower.
