摘要： A cut and cover method of constructing grade separation structures includes partially burying precast substructure elements with associated trench boxes under live traffic. Once the precast substructure elements are buried, the substructure is completed and the bridge span is installed. Other methods include installing precast superstructure elements with a formwork system and forming a bridge substructure and excavating underneath the superstructure once the superstructure is formed.
