Night-time lane reductions on the A4 motorway

In order to ensure operations over the next 15 to 20 years, the Federal Roads Office (Astra) is repairing the motorway section between the Rütihof junction and the Küssnacht junction in three stages between 2025 and 2027.

The road surfaces along the entire stretch will be replaced with low-noise surfaces and the crash barriers, fences and operating and safety equipment will be renewed.

Due to conversion work, the A4 southbound carriageway will only have one lane on two nights               Image: Google Maps
