The design of interurban intersections on major roads
At - grade intersections
The document "Interurban junction design – grade intersection" is a technical guide for designing grade intersections on main roads outside urban
areas.
The document "Interurban junction design – grade intersection" is a technical guide for designing grade intersections on main roads outside urban areas.
It follows the more general guidelines given in the document "Main Road Development" and provides further principles to be taken in account when developing projects for new infrastructure or the improvement of the existing network, together with the method to be used for selecting the junction type. It makes recommendations for defining the geometric aspects of the projected developments and improvements.
