Swiss Transport Network Faces Major Restructuring

Switzerland is embarking on a comprehensive restructuring of its national transport network, with the federal government commissioning a detailed report from ETH Zurich to guide future infrastructure priorities. This initiative represents one of the most significant overhauls of Swiss transport infrastructure in recent years, addressing both rail and road networks across the confederation. The Federal Council's approach aims to create a more integrated and efficient transport system while responding to current infrastructure challenges and public concerns.

The restructuring initiative emerges from a complex backdrop of public rejection of motorway expansions and mounting concerns over infrastructure costs. The Swiss electorate's previous rejection of motorway expansion plans has forced a reassessment of transport development priorities. Additionally, the rail sector faces significant challenges with unexpected cost increases in ongoing expansion projects. These factors prompted Transport Minister Albert Rösti to commission the ETH Zurich report, led by Professor Ulrich Weidmann, to provide expert guidance on future development strategies.

The government has outlined a clear timeline for implementing the transport network changes. By January 2026, the environment and transport ministry will present detailed proposals for both national roads and rail infrastructure expansion. The implementation is structured in three main phases: 2027, 2031, and 2035, allowing for systematic development and adjustment. A draft consultation text is expected by the end of June 2026, with separate referendums planned for rail and road projects to ensure democratic oversight of the process.

The financial scope of this restructuring is substantial, with approximately CHF 14 billion ($17.4 billion) in additional costs anticipated for the approved railway expansion phase alone. The ministry is developing proposals that consider increased revenue streams while adhering to federal savings package requirements currently under parliamentary discussion. Road projects and agglomeration programmes will be designed within existing financial frameworks, reflecting a careful balance between development needs and fiscal responsibility.

The restructuring will significantly impact Swiss mobility patterns and urban development. The government's approach of bundling expansion steps for road and rail with agglomeration transport programmes demonstrates a commitment to integrated planning. While separate referendums for rail and road projects ensure democratic participation, they also reflect the complexity of gaining public approval for major infrastructure changes. The success of this restructuring will largely depend on balancing regional interests, environmental concerns, and economic efficiency while maintaining Switzerland's high standards of public transport service.
