Key facts
The FEDRO had planned to widen the motorway between Le Vengeron and Nyon to three lanes in each direction. The section concerned is approximately 20km long. The aim of the widening was to eliminate existing bottlenecks and it was also intended to improve traffic flow and increase safety.
The Federal Council approved the general project in October 2023. The project was scheduled to be completed in 2032 at the earliest and the estimated cost of the project was nearly CHF 1 billion.
The SFAO assessed the progress of the project as part of its audit. The project was on track until the vote on 24 November. Improvements were needed in the areas of organisation, cost management and quality.
| DISCLAIMER The audit by the Swiss Federal Audit Office (SFAO) took place before the federal popular vote on 24 November In the vote, the people rejected the federal decree on the 2023 development stage for motorways by 52.7%. The six motorway projects will therefore not be implemented. As a result, the Vengeron-Coppet-Nyon (VCN) project, which was audited by the SFAO, will not go ahead. However, the audit findings can be used for other projects currently underway or planned by the Federal Roads Office (FEDRO). The recommendations should be used to continuously improve road infrastructure project management, drawing on the best practices referred to in this report. The recommendations in the report were adapted in consultation with the FEDRO after the final discussion so that they could provide added value to the FEDRO for its other motorway projects. A deliberate decision was taken not to rewrite the report itself. |
