Roads made of recycled plastic and snapped together like LEGO's? And cleaning the world's oceans too?

From the blog Inhabitat is this about the possible future of roadways in Rotterdam:

     VolkerWessels’ roads would consist of an easy snap-together design, much like Legos, which could be easily accessed for repairs. The roads could also be moved around to different locations, an unprecedented innovation that is especially perfect for the Netherlands’ sandy or swampy terrain. Inside the prefabricated bricks would be a hollow space, creating opportunity for easily accessible infrastructure. While the development is still years away, it is exciting to know such creative approaches are being taken to address solutions to widespread environmental destruction.

The post includes images of the plastic roads and how space is manufactured into the product for infrastructure.
