Are they any car map apps that can deal with roads that are cut off by showing an alternative way?
Say you plan a trip on the road app that has a train line, the boom gates fail and are down, you drive to the next rail crossing only to find that the boom gates there are down as well and have have blocked passage.
Along the rail line are tunnels, under passages, bridges over passes etc, can a map app show a alt route using those?
If any, which app?
