This article looks back to the development of grade separations in cities of China in the past half of the century, based on which, the existing problems in provision of grade separations are raised for the purpose of guiding the construction thereof to a virtuous circle.

This essay starts with an inquiry into the structural formations in FANF Fangs novels, which are illustrated by the synchronism of the present and history, the network of grade separation and the agreement of the concrete with the abstract.

The traditional grade separation form will cause some problems during the design process due to the terrain condition limitation.

Adopting fly over crossing coordinating method and scheduling the coordinating time of various professional workers the engineering can be completed in l.

In allusion to the conflict points calculation and driveway setting in provincial and national main line grade crossing design as well as the main problems of traffic safety existing in constructed grade crossing, some design ideas and improvement projects are proposed in a view ofengineering design, which can be consulted by designers.
