Situated in Munich-Bogenhausen, the tunnel forms part of the Mittlerer Ring ring-road, and also connects to the A94 autobahn.
But warnings are circulating in the press and on the Internet about the 12 speed-cameras, permanently installed in the tunnels. Called "Geisterblitzer" in German, these digital cameras are equipped with an infra-red flash, invisible to the human eye. Drivers won't know when the cameras are active, and also won't know if they been caught, until the fine notice arrives in the post.
