(Buildable) Road systems. Within the Build menu, a new option for "Roads" will appear, acting similar to the buildable pool water, as it will dig a few studs down into the ground, and create a platform, much like the roads that appear all over Bloxburg city's streets.

Within the "Roads" building option (or perhaps elsewhere if more convenient) another placable object will appear, titled "driveway" (or something similar) that can only be placed at the edge of your plot. (similar to the mailboxes) It will extend any nearby road systems out of bounds and onto the real Bloxburg street (in other words the street baked into the map), making a smoother transition from plot to street. Admittedly, this may take a bit of recoding and redesigning streets however, moreso to get sections of the sidewalk to disappear if the driveway item is placed over it.

Finally, other pre-existing road objects can be moved to the new Road tab, most importantly the "road marking" decals and crosswalk markings, as their main purposes are directly tied to the roads.

Thank you to whomever reads this, and especially a thank you if any of this concept is added!
