context_page_description: The Tōmei Expressway is a national expressway on the island of Honshū in Japan. It is operated by Central Nippon Expressway Company. The expressway is designated as E1 under the "2016 Proposal for Realization of Expressway Numbering", because it parallels National Route 1. It is a part of the Asian Highway Network.
context_section_description: Sections with left and right routes formerly carried 2 lanes of traffic in each direction. An additional roadway (carrying 3 lanes of traffic in one direction only) has been constructed parallel to the existing 4 lanes to alleviate congestion. The original 4 lanes are then converted for the use of traffic in the opposite direction.
