The Shin Tōmei highway ( Japanese 新 東 名 高速 道路 , Shin Tōmei Kōsokudōro , dt. "New Tōmei highway") is a 162-kilometer highway on the main island of Honshū in Japan that has been partially opened since 2012 . It runs about 10 km further inland and parallel to the longer Tōmei motorway , which connects Tokyo and Nagoja , and is intended to relieve this as currently the most important east-west motorway and to be completed by 2020 on a total length of 254 kilometers. The motorway is tolled and operated by the Central Nippon Expressway Co., Ltd. ( 中 日本 高速 道路 株式会社 , Naka-Nihon Kōsokudōro Kabushiki Gaisha , NEXCO Naka-Nihon ( NEXCO 中 日本 ), English NEXCO Central Japan ) operated.

Planning, implementation and expansion

After the route was determined in 1987, the planning extended to the start of construction in 1995. After 17 years of construction, the first 162 km long section in Shizuoka Prefecture between Gotemba in the east and Mikkabi ( Kita-ku district of Hamamatsu ) in West to be opened. The expansion in the west to the city of Toyota in Aichi Prefecture is to be completed by 2015 and in the east to the city of Ebina in Kanagawa Prefecture by 2020 . Currently, the highway is connected to the Tōmei highway at its ends.

Due to the route chosen further inland, the Shin Tōmei highway should be less susceptible to possible earthquakes and tsunamis triggered by them than the Tōmei highway, which had to be partially closed after the Tōhoku earthquake in 2011 . To optimize fuel consumption and to ensure safety, the maximum gradient was limited to 2% (Tōmei motorway 5%) and the minimum curve radius increased to 3,000 m compared to the Tōmei motorway (300 m). The tunnel lighting and traffic monitoring were also improved compared to the Tōmei motorway, the number of helicopter emergency landing sites is 12 (Tōmei motorway: 2).

To realize this in the very mountainous area, it was necessary to lead the motorway through a large number of tunnels and over several bridges and viaducts . In addition to the landscape, the strong earthquake hazard in the region had to be taken into account. In the interests of the economic viability of this non-state, toll motorway, cost efficiency was an important criterion. State-of-the- art construction and construction techniques were used for this, such as the use of an extradosed bridge , prestressed concrete box girder bridges with additional inclined pressure struts to support the cantilevered carriageway slabs and the combination of prestressed concrete structures with steel supporting structures to minimize the dead weight. The eight bridges listed in the table below have received the Tanaka Award from the Japan Society of Civil Engineers (JSCE) for excellence in bridge construction.

In the first six months after the opening of the 162 km long section, the volume of traffic was distributed in roughly equal parts on the two parallel Tōmei motorways in this area and increased by a total of around 16% to 84,800 vehicles per day. The volume of traffic on the older Tōmei highways could thus be reduced by 40% to 43,800 vehicles per day (73,300 vehicles per day in the same period in 2011). As a result, there were only eleven traffic jams of more than ten kilometers on both motorways , compared to 148 on the Tōmei motorways in the same period in 2011. The average travel speed increased slightly, the number of traffic accidents decreased by around 10% .
