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.Official "flyer" updated with the top photo showing the central span being added. At the bottom is an illustration of the constraints from air and sea. {{cite web |url= http://www.pa.ktr.mlit.go.jp/tokyo/blog/pdf/sin_leaf20110311.pdf|title= 【最新版】TGBチラシ_H23.3.3_|trans-title= Tokyo Gate Bridge latest update 3 March 2011|date= 2011|publisher= Ministry of Land, Infrastructure, Transport and Tourism|location= Japan|language= Japanese|archive-url=https://web.archive.org/web/20111008153047/http://www.pa.ktr.mlit.go.jp/tokyo/blog/pdf/sin_leaf20110311.pdf |archive-date=8 October 2011 |url-status=live |access-date= 6 June 2011}} The resemblance of the bridge to two monsters facing off has given it the nickname of {{nihongo|'Dinosaur Bridge'|恐竜橋|Kyōryū-bashi}}{{cite news |author1=Cooper, Chris |author2=Matsuda, Kiyotaka |agency=Bloomberg |url=http://www.japantimes.co.jp/news/2012/02/12/business/dinosaur-bridge-leads-tokyo-push-to-ease-traffic-and-boost-economy/ |title='Dinosaur Bridge' leads Tokyo push to ease traffic and boost economy |newspaper=The Japan Times|date=12 February 2012 |page=2 |access-date=3 August 2016 |archive-url=https://web.archive.org/web/20130430010908/http://www.japantimes.co.jp/news/2012/02/12/business/dinosaur-bridge-leads-tokyo-push-to-ease-traffic-and-boost-economy/ |archive-date=30 April 2013 |url-status=live}}

Visitors can take an elevator to the sidewalk on this bridge and walk on the sidewalk from Wakasu to Central Breakwater. But, you can only take an elevator to the sidewalk and the ground from Wakasu Gate, because Central Breakwater Gate is closed, so you cannot take an elevator to sidewalk and ground from Central Breakwater.

If you want to only see the bridge, you go to [https://www.tptc.co.jp/en/c_park/03_07 Wakasu Seaside Park] and Central Breakwater.

The bridge can be accessed using the Wakasu Seaside Park Bus stop which 木31 - Shin-Kiba Station（Toei Bus passes through. The Central Breakwater Bus stop can also be used, which 波01 - Tokyo Teleport Station（Toei Bus）passes through. ※From Central Breakwater gate you cannot walk on the bridge.
