ADAC warns of record traffic jams on Gotthard tunnel and German highways this August

The German automobile club ADAC predicts severe congestion on the Gotthard tunnel at the start of August, with estimated wait times of up to three hours on the weekend and advises drivers to use alternative routes such as the A13 San‑Bernardino corridor or the Gotthard Pass (not recommended for vehicles with camping trailers).

ADAC’s broader summer‑traffic forecast for July 31 – August 2 shows heavy traffic on southern corridors including the Brenner, Tauern and Gotthard routes, compounded by about 1 000 construction sites and occasional road closures.

The forecast cites the longest traffic jam ever recorded in Germany – a 77‑kilometre standstill on the A61 in early 2024 – underscoring the scale of expected delays for holiday‑making motorists across Germany and Alpine transit routes.
