Completely immersed in the greenery of the trans-Apennine stretch between Emilia and Tuscany, the suggestive curve of the Poggettone and Pecora Vecchia overpass crosses over the two homonymous creeks, like many other overpasses (Aglio, La Quercia, Biscione, etc.). They take their curious names from Francesco Aimone Jelmoni’s imagination, professor at the Polytechnic of Milan, designer of the preliminary project of the higjway (scale 1: 25000) that had to walk the route several times, to confirm the choices made on insufficient cartography.
The structure is broken down into six parallel planes, cut out into squares like sheets of paper. Between an openwork pylon and the other, the line of an arch seems to be designed by Maillart, whom the designers are always inspired by.
