Appreciation towards JBMC for providing the following description:

Cidade Nova is a metro station located on Presidente Vargas Avenue, Gamboa, downtown Rio de Janeiro. Already under construction in a stretch of elevated tracks, Cidade Nova will enable the integration between the two existing lines, playing a key role in the 2014 FIFA World Cup. Gamboa is a century-old district decaying in spite of its rich infrastructure. Presidente Vargas Av., one of the city’s widest and busiest avenues, imposes a physical barrier to its revitalization, revealing the need of a connection between both sides.

In attempt to connect Gamboa with the major corporate buildings on the opposite side, a 207 meter-long covered footbridge was designed allowing both pedestrian crossing and bus-metro integration. Supported by only three long-span steel arches with entwined bases, two of which are 90 meter-long and one, 40 meter-long. Being close to world-famous Sambódromo, the 6 meter-tall soffit will allow float passage. Adequate lighting will guarantee the noble-metal tones of the structure to be enhanced at night.

The choice of the constructive methods and materials took local constraints into account. Aiming to disrupt traffic minimally, the steel structure enables part of the assembly to be produced elsewhere shortening the work at the construction site. In the station itself, a row of arches support the mezzanine, allowing a pillar-free platform. The connection between the station and the footbridge takes place in the mezzanine, which, in the future, may also be connected with a nearby coach terminal.

Open to the external environment, differing from others, this station will make use of natural ventilation. Allied with leveled-up practices for insulation, lighting, solar water-heating and rainwater garden irrigation, the Cidade Nova station will save a considerable amount of natural resources.

JBMC Architecture was chosen by Metro Rio, metro system concessionaire, due to their large experience in metro station design. Sustainability criteria were agreed upon by the client and JBMC.

Cidade Nova是位于里约热内卢市中心甘博亚的巴尔加斯大道的一个地铁站。一个新构筑物需要整合正在铺设的高架轨道和现有地铁线路，以便迎接2014的世界杯。

甘博亚是一个基础设施完善的古老区域，城市最繁忙的道路途径这里，形成天然划分区域的物理屏障，新的构筑物联系道路两端，释放出该地区更大的活力。

一个长达270米的人行天桥出现了，并整合行人，巴士，以及铁路交通。三个大跨度的拱将大桥支撑起来，其中两个长90米，另外一个长40米。因为离世界闻名的传统嘉年华举行地Sambódromo非常近，所以桥体被设计成离地6米，允许嘉年华队伍通过。照明设计为桥体金属构架在夜间观赏时增色不少。

施工建设考虑到当地实际情况，钢结构在其它地方成产好在到现场组装大大缩短了建设周期。桥的设计也为未来客运站的联系做了预留。通体采用开放环境，进行自然通风。将照明，太阳能热水以及雨水花园灌溉系统并入设计，这个新的转换站节省了大量的自然资源。

JBMC建筑事务所因为具备大型地铁站的设计经验，而被里约地铁部门钦点御用。客户与建筑师一共制定了可持续发展原则。
