Cavalcavia Monte Ceneri-Serra, Elevated road in northwest Milan, Italy.

The Cavalcavia Monte Ceneri-Serra is an elevated viaduct that connects Viale Monte Ceneri with Viale Renato Serra in northwest Milan. The 1800-meter structure consists of two separate viaducts, including one that spans 350 meters over another street and another that extends about 1 kilometer before reaching the Ponte della Ghisolfa bridge.

Built between 1959 and 1965 to a design by engineer Silvano Zorzi with Giorgio Macchi, and constructed by Angelo Farsura, the viaduct opened in stages: the first section, the overpass of Viale Renato Serra at Scarampo and De Gasperi, opened to traffic in April 1961. Even then, the ban on heavy vehicles, chosen to keep the deck slender, was criticised for favouring appearance over function. A plan to extend the elevated road around the whole outer ring was realised only on the adjacent stretch of Viale Monte Ceneri, then halted because of serious urban integration problems.

The deck's cross-section narrows toward the outer edges, so from street level the viaduct reads as a thin continuous ribbon above the avenues. The choice of slender central piers was deliberate: heavy vehicles were banned from the structure to keep the section lean, a decision already criticised at the time of construction as putting aesthetics before function.

The viaduct starts at Piazza Stuparich and runs northeast along the outer ring road. The first 350-metre span crosses Viale Scarampo, which carries the Autostrada dei Laghi into the city; the second, about 1 km long, follows Viale Serra and Viale Monte Ceneri to the Ponte della Ghisolfa. Heavy vehicles are banned from the elevated roadway.

Heavy vehicles were banned from the viaduct at the time of construction so the deck could be slimmer; critics then argued that aesthetics had been favoured over functionality. The deck's thickness decreases toward the outer edges, which is why the viaduct reads as a thin continuous ribbon.
