Today, approximately 250,000 residents of Salzburg and its surrounding regions are voting on the S-Link project, a proposed 17-kilometer underground extension of the local railway.

This infrastructure initiative aims to alleviate the city's chronic traffic congestion, which affects thousands of daily commuters and tourists.

Proponents view the S-Link as a 'once-in-a-century opportunity' to modernize Salzburg's transport system, while opponents criticize it as a potential financial burden, with costs estimated between 1.9 and 2.8 billion euros.

The project promises to reduce car dependency and improve public transport, but concerns over high costs and potential disruptions during construction persist.

The outcome of this vote will significantly influence Salzburg's future urban mobility strategy.
