This project integrates urban park and community entrance to sets up a three-dimensional traffic mode. There are three main challenges to be consider: First, how to activate innovation of the city interface. Second, how to bring popularity to the area. Third, how to sort out complex traffic flow lines. Starting from the dimension of time shuttle and art freshmen, the design uses geometric elements to intangible design logic. Light was put into the function of runway and footpath as a bridge，and grass was sloped to shape the site into an interesting exploration terrain.
