Gardesana Occidentale - Il Meandro

Where cliffs once made a shore road impossible, engineers carved the Gargnano–Riva stretch of the SS 45 bis between 1929 and 1931. Gabriele D'Annunzio christened it Il Meandro, tunnel mouths received mythological names, and its planted belvederes frame views across the lake.

Why it matters

For centuries the western shore of Lake Garda ended at Gargnano: north of town, rock faces plunged straight into the water, and the villages beyond were reached by boat or mountain path. The road that finally closed the gap — built between 1929 and 1931 to the design of engineer Riccardo Cozzaglio — was conceived from the start as something more than infrastructure. The municipal portal describes a strada-parco, a park road camouflaged into the landscape with exceptional technical skill, planted with more than a quarter of a million trees and punctuated by panoramic lay-bys. At its inauguration it was proclaimed the most beautiful road in Europe, and D'Annunzio, its most famous champion, gave it the name by which the Gargnano stretch is still known: Il Meandro, the meander, for the way it winds between dark tunnel and open water.

What to notice

Three registers of design define the road's character. The first is engineering: the route required excavation on a scale unusual for its day — around two thousand workers dug some nine hundred thousand cubic metres of rock, and the road's seventy galleries, over seven kilometres of them in total, remain the defining rhythm of the drive. The second is nomenclature: D'Annunzio supplied the mythological names of the rock-cut tunnels, giving the road a classical vocabulary that carries his chosen name. The third is vegetation and outlook: the tree-planting scheme and the piazzole-belvedere, the panoramic lay-bys, were part of the original project, not later decoration, framing views of the lake north of Gargnano as the designers intended. The modern alignment, long tunnels, rockfall barriers and widened sections record decades of change; older carriageways sometimes remain visible beside or below it.

Context and history

The road answered a need that had become strategic. Wartime experience from 1914 had shown the value of a shore connection toward the front near Riva, and the project for the Gargnano–Riva stretch took shape in the mid-1920s under Cozzaglio, with construction running from 1929 to September 1931 across six great construction sites. The official portal records the total route at 27 kilometres; an exhibition study of the road's history puts the figure at 28, a discrepancy of sources that public copy brackets. Inauguration followed on 18 October 1931, attended by D'Annunzio, who had promoted the work alongside Mussolini and had baptised the road with its meander name. The Second World War gave the tunnels a second life, as weapons factories were relocated into them against Allied bombing — a chapter documented by the Alto Garda museum's photographic exhibition on the road. Growing traffic later forced repeated modernization: the portal lists long tunnels, rockfall protection, widenings and the abandonment of lengthy parts of the original alignment, yet concludes that the architectural, structural and vegetational character of the strada-parco remains legible, a linear landscape of exceptional value.
