Commissioned by the South Korean Railroad Research Institute (KRRI), architectural studio ZJA, Woosung D&C, C&SC, GS E&C, SIDstudio and Iv-infra came up with an above-ground solution for an  elevated light rail track in a packed city environment, with less spatial impact than the traditional design. 

Innovative structural concept

The innovative structural concept of the Elevated Light Rail Transit makes a maximum span possible, while being extremely strong and dimensionally stable. The solution was found in a slim design with a limited construction height, based on the principle of the I-beam profile. 

The use of a central beam between the tracks, with flanges cantilevered outwards, makes it possible - even at places where the structure is around fifteen metres high - to extend the distance between columns to 200 metres without the need for extra stays or cables.

Elegant design and liveability

Strong, able to retain its shape and giving passengers a completely open view on one side, the design features transparency and spaciousness, reduces traffic congestion, and leaves room for pedestrians and green space. The network resembles a tendril and its light and animated volume winds across the metropolis at a great height. 

An asset to the city, and to the people who live, work and travel in it. Does this sound like a dream? A full-scale 40-meter sample and several scale models have already passed their first tests for stability, and for resistance to wind load and to earthquakes.
