A modern road tunnel portal offering strong leading lines, repeating geometry and textured concrete — ideal for minimalist, architectural and light‑trail shots. Best visited at blue hour or night for vehicle light streaks; after rain for reflective surfaces. Accessible from the roadside in Gretzenbach; watch traffic, use safe pullouts or nearby parking and never stop in active lanes. No special permits for exterior shots, but respect local traffic rules and neighbors.
