Pomy tunnel

The Pomy Tunnel , together with the Arrissoules Tunnel, is the longest tunnel on the Swiss A1 motorway .

It is located in French-speaking Switzerland on the Bern – Lausanne section between the Estavayer-le-Lac and Yverdon-les-Bains connections. The two-tube tunnel measures 2958 meters and 3005 meters and is located in the canton of Vaud . It crosses under the municipality of Pomy in the gently undulating western Swiss plateau.

The tunnel was built as part of the expansion of the last section of the A1 between Payerne and Yverdon-les-Bains. It was opened in 2001 after several years of construction. Not only topographical, but also environmental causes were responsible for the construction of this relatively long tunnel.
