Hong Kong features two large bridges, the Ting Kau Bridge and the Tsing Ma Bridge. Both do have some unique design elements that make them either the longest or the first of their kind - but that's better explained in the above provided Wikipedia links.
Usually shots of these bridges are taken from the Lantau Link Visitor's Centre, it's vicinity or from Tung Wan Beach on Ma Wan (Park Island). But from these spots it's impossible to shoot both bridges together.
If one wants to get something new, then photography is mostly footwork. The two shots below show a different perspective - and both bridges together are featured in the pictures.
