The proposed expansion of Swiss national highways, set for a vote on November 24, has sparked significant debate.

Proponents argue that the expansion will reduce traffic congestion and enhance safety.

However, internal documents from the Federal Roads Office (Astra) contradict these claims, suggesting that additional lanes may actually decrease safety.

Astra's analysis indicates that only a small fraction of highway accident hotspots exist, and expanding lanes could increase accidents.

Meanwhile, public opinion remains divided, with recent surveys showing a narrow majority in favor of the expansion, but with significant opposition citing environmental concerns and urban sprawl.

The political landscape is polarized, with support largely from rural areas and conservative parties, while urban and progressive groups express skepticism.
