1. I want to note that the MD 615 line does end up south of I-70/US 40.
Nothing a little shaping point won't fix!
Also, hey, the south end of MD 615 really should have a graph connection with I-70 shouldn't it? Now it shall.
2. I want to note that the MD 17 line ends up north of I-70 briefly southeast of the interchange. (where MD 17 should remain south of I-70)
Fixed by adding a couple shaping points to I-70.
3. The concurrency with US 40 is broken as US 40 has *I-70(54) while I-70 does not. (Looking further, it seems to be the result of removing this point on I-70 so it should be removed from US 40.)
Well that's a whoopsie.
I agree with yakra that since *I-70(54) is in use that removing it (or making it the label for the new exit 54 location) would not be ideal. That said I like that on I-70 it was possible to put 54 in the currently correct location since it wasn't in use and am not inclined to undo that.
So, point added back to I-70, named "*Old54".
