若采用常规的架空线路跨江，需要在长江江面树立两个超450米的巨型铁塔，而且要为每个铁塔建一个超四个足球场大小的人工岛。
If conventional overhead lines were used to cross the river, two giant iron support towers more than 450 meters in height would need to be built on the Yangtze River, and an artificial island larger than four soccer fields would need to be built for each tower.
