This section there is a cross intersection. The concrete surface is divided into linear design, longitudinal design, crosssectional design, intersection design, Pavement design, lighting and drainage design. Plane line using Municipal detailed rules established by the planning alignment, line northsouth direction, along the road and turn the starting point, Di Tang, Binhai Road, intersection, across the center Yokoe planning river. According to local planning requirements and with the actual situation, as the straight plane line, no horizontal curve. Focus on crosssectional design, the intersection of vertical curve calculations and detailed design calculations. This design from the short and long term traffic needs, considering the population growth in the next few years and vehicle traffic changes, so that the New to better integrate into Shanghai, Hangzhou, Ningbo, 2hour traffic, do to peopleoriented, followed the principles of sustainable development. Xingci all the way to the design speed of 40km / h, a total line length , twoway road in the form of four sixlane road, lane width meters. There are flat across the curve 0, vertical curve 6. Pavement thickness of 680mm of asphalt concrete pavement.
