Shuto Expressway



Shuto Expressway (首都高速道路) is a network of toll expressways in the Greater Tokyo Area of Japan. It is operated and maintained by the Metropolitan Expressway Company Limited (首都高速道路株式会社).

Most routes are grade-separated (elevated roads or tunnels) and central routes have many sharp curves and multi-lane merges that require caution to drive safely. The speed limit is 60 km/h on most routes, but 80 km/h on the Bayshore Route, and 50 km/h on the Inner Circular Route.

All trips on the expressway require a toll be paid. As of 2014, the cash toll for a standard-size car is ¥1300 regardless of distance traveled. Vehicles using the ETC toll-collection system pay a distance-based toll ranging from ¥300 to ¥1300 for ordinary vehicles (see toll price) – in some cases substantially less than the previous fixed-rate toll. Lower cash rates exist for certain radial routes (where there are only a few kilometers of expressway remaining) and ETC users have various time-of-day discounts. For large vehicles, the toll is doubled.

History
The Metropolitan Expressway was first built between Kyobashi Exit in Chūō, Tokyo and Shibaura Exit in Minato, Tokyo in 1962 for the purpose of increasing traffic flow efficiency in the Tokyo Metropolitan Area, thus optimizing and improving the functionality of the traffic system. Since then, 280 kilometers of highway network has been built in the Tokyo metropolitan area; 30 kilometers more of highway are either constructed or planned, making the Metropolitan Expressway a vast network of urban expressways in the Tokyo region.

Pillion passenger ban on motorcycles
Japan allows a person aged at least 20 who has held a motorcycle driver's license for at least three years to carry a pillion passenger on expressways, however, the Shuto Expressway in the central parts of Tokyo prohibit carrying pillion passengers due to poor road geometry. The ban does not apply if the motorcycle is equipped with a sidecar. The segments with a pillion ban include the important C1 Inner Circular route and adjoining central Tokyo routes.

With the opening of the C2 Yamate Tunnel, motorcycles with a pillion passengers can finally pass through the Shuto Expressway from the national expressways such as Tōmei Expressway to other expressways using the C2 route, although this can be a much longer drive in some cases.

Parking areas
There are 21 parking areas scattered throughout the Shuto Expressway system. In general these are much smaller than the service areas available every 30 km or so on inter-city expressways. In some cases there are no more than toilets, a few vending machines, and a handful of parking spaces. None have fuel – drivers must exit the system (and pay the toll again on re-entry) to use a service station.

Street racing
Like other expressways in Japan including the Tōmei Expressway, the Shuto line has become a common street racing road. One of the lines, the Bayshore Route (also known as the Wangan route), received worldwide notoriety during the 1990s as the home course for the Mid Night Club, one of the most notorious street racing clubs, who were known for their 300 km/h, sometimes 320 km/h exploits. These exploits and street racing culture on the Shuto Expressway have made it a well-known location for street racing and speed records.

Due to this infamy, the Wangan is the setting for several entertainment franchises, such as the manga and arcade game Wangan Midnight, video games Shutokou Battle and Gran Turismo 5, 6, Sport and 7 (as the street circuit) and the movie series Shuto Kousoku Trial. Numerous car enthusiast magazines and DVDs, like Best Motoring, also highlight races and activities on the Wangan.

Ohashi Junction


Ohashi Junction (大橋ジャンクション) is a One-quadrant Interchange in Shuto Expressway system in Tokyo. It connects Shibuya Route and Central Circular Route. It's built in 2010 partially, and fully completed in 2015. It's an indoor type Interchange and covered in concrete walls.

It is designed as compact as possible and environmentally friendly. Shibuya Route is an eleveted highway and Central Circular Route is an underground one. So, it is Helixshaped and you would drive in circle 4 times to transfer. There is "Meguro Sky Garden" and chimney on the roof.

Dimensions

 * Above ground : 35m
 * Under ground : 36m
 * Diameter : 175m - 130m
 * Meguro Sky Garden : 7000m2
