The whole of SR 844 is technically a freeway, and toll plazas/entrance gates are usually included as part of the freeway for consistency. Even if you're coming off or going onto the road for just 100 feet, it's still part of the gate approach along the freeway.

But on another note related to this changeset - where does the name 'A Road' come from for the roadway between SR 844 S and SR 444? Maps that I've searched up indicate that the name of this road is actually called Davis-Monthan Road (though it appears that it isn't signed with any name and appears more as a highway ramp, so it can't be confirmed 100% if this is the real name of it). Was this name sourced from Google Maps?
