The proposed Rheintunnel in Basel has become a focal point of controversy as Switzerland prepares to vote on the expansion of national roads.

Proponents argue that the tunnel will alleviate traffic congestion and reduce noise and pollution in local neighborhoods by diverting traffic underground.

However, traffic experts caution that the Federal Roads Office may be overly optimistic about the tunnel's long-term impact, suggesting it could lead to increased traffic.

The project has also faced criticism from local youth, who protested during a visit by Federal Councillor Albert Rösti, expressing concerns about the tunnel's environmental impact and its alignment with climate goals.

Despite the school's administration supporting the project, students voiced skepticism, highlighting the potential for increased CO2 emissions and questioning the project's relevance in light of Basel's climate neutrality targets.

The Rheintunnel, part of a broader infrastructure plan, is estimated to cost 1.87 billion and is expected to be completed by 2040.
