Tokyo Gate Bridge

It opened on 12 February 2012[1][2] with an estimated total construction cost of 113 billion yen for the Stage II section of highway including the bridge.

[3] Part of a new four-lane highway ringing Tokyo, construction began in 2002 and was scheduled for completion in 2011, but the opening to traffic was delayed until 2012.

With the provisional name of Tokyo Bay Waterfront Bridge (東京港臨海大橋, Tōkyōwan Rinkai Ōhashi)[4] the public was asked for suggestions.

[5] The design fulfils the requirement to be high enough to allow large ships to pass underneath, but low enough not to interfere with air traffic to the nearby Haneda Airport.

It is a double cantilever bridge, which means that the truss sections from either side can be completed in balance, and then joined by the addition of the relatively short central span.
