We describe an interactive system that provides support for the geometric design of roads. The several steps of road design are considered, together with the necessary geometric modeling tools. The user interface tries to simulate and improve the methods traditionally used for road design, by providing four views integrating all designing phases and giving immediate feedback when a change is made in any of them.
