Dallas: Mapping the Underground

Dallas has a neat little underground tunnel system called the Dallas Pedestrian Network.

Unfortunately, Google Maps doesn't show the tunnel system so I took it upon myself to make an interactive map in My Maps, based on the static map available on the wikipedia page of the network. 

Click the ⭐️ next to the title to add it to your Google Maps app, you will be able to find it in your "my maps" tab.
