Wide 4-Way Int.
If one branch off is good, then two is even better. The Wide 4-Way Intersection adds the option to branch off two standard size corridors from your string of wide corridors. Intermix any combination of Wide T or Wide 4-Way Intersections in a single string of wide corridors as long as they are each separated by at least one Wide Corridor. And as with all Bug Hunt Corridors, the corridors you branch off will match up correctly elsewhere in your layout.
