Switzerland is gearing up for a significant vote on the expansion of its national highways, with a campaign launched by an alliance of economic and conservative parties.

The proposed projects aim to alleviate traffic congestion, enhance safety, and reduce environmental impact through strategic expansions, including tunnel constructions.

The Swiss government estimates that traffic congestion costs the economy 1.2 billion francs annually.

The expansion is seen as crucial for economic growth and mobility, with proponents arguing it will benefit commuters, businesses, and the overall economy.

However, the proposal faces strong opposition from left-leaning parties and environmental groups, who have initiated a referendum against it.

The outcome of the vote, scheduled for November, will be pivotal in shaping Switzerland's transportation infrastructure and addressing the pressing issue of traffic congestion.
