Pearl River Necklace by NL Architects

In mainland China you drive on the right side of the road. In Hong Kong you drive on the left. So what happens when you drive from the mainland to Hong Kong? Or vice versa? If NL Architects had their way, the transition would be both seamless and graceful.

The bridge design of their Pearl River Necklace proposal turns the road into a figure-8, sweeping out, over/under, and together again, shifting motorists effortlessly to correct side of the road.

Here is how NL Architects describes the idea behind the bridge design: "Pearl River Necklace is an attempt at untying the knot. It is a breakdown of the complexities of the Border Crossing Facilities into a 'Necklace of Shining Pearls. The objective is to bring to the surface the intrinsic beauty of the HKBCF and at the same time to reinforce the attractiveness of the projected Hong Kong-Zhuhai-Macau Bridge."

They pose the question: "Can we turn the moment of swapping into an unforgettable spectacle? Can we enhance awareness of motorists while at the same time creating an unprecedented driving experience?"
