The Saint Martin d'Estreaux giratory, on the N7 road, at west north of Roanne (F)
owned a great dangerosity reputation.

Its greened dome was confused with slopes around it.
Many drivers discerned it too late.

The road departement Office of loire asked me to interfere
as part of our research and contribution in the
"pacified road concept" 

I have made this giratory as a symbollically lived site,
proposing to the users a poetic and convivial atmosphere to concern them and to awake their attention, night and day.

Materials and conception of theses sculptures make the group inoffensive if, by accident a car would cross the giratory.

The carrying out of an economical usefull building system
make possible, after an eventual accident, that the same work can be rebuilt by the DDE of Loire services.
