Not sure if this is a bug per se, but when you load the page you start at https://mbtashutdowns.info/all. Then if you click on one of the shutdown bars:
it takes you to the page for that shutdown.
Then when you click back
It sends you back to the line-specific page i.e. https://mbtashutdowns.info/orange
I think that could be a little disorienting. I would propose the site remembers whether you came from a line page or the all page and sends you back accordingly.
