Thank you for this suggestion. I can use it for the bridges (for which I did not have a nice solution yet). But for the tunnels the goal is not to add an indicator for a tunnel, but to use one single dashed line for all tunnels, but with different Garmin routing properties. That's why I list them all. I could have shortened the list, but this way it is an altered copy of all the original ways and easier to maintain.

You could do this with one line as a layer on top of each highway: (tunnel=yes | tunnel=true) & (railway!=subway | waterway!=*) [0x12 resolution 23 continue with_actions] This way you don't need to specify each road with a tunnel tag separately. In the typ file it is rendered as a transparent bitmap with two dashed lines with enough space in between to render the highways: --- 8< --- snip --- 8< ---
