“Grade-separated intersections” refers to the various means of significantly increasing the
capacity or resolving physical constraints by grade-separating the through movements on
two in-tersecting roadways and interconnecting the two with ramps or roadways that form
one or more intersections. Concepts and designs are discussed that have been successful
in resolving in-tersection capacity problems and geometric or physical constraints in a
manner responsive to the various needs and requirements of individual locations. Guidance …
