I assume that roundabout will be a lower cost, temporary connection between the 2-lane Belle Vista Bypass and I-49.
There's no way that thing is going to fly as a permanent connection once the Belle Vista Bypass is 4-laned, fully built out to Interstate standards and intended to be marked as I-49. That kind of "Breezewood" might prevent the bypass from being called I-49 unless the roundabout is replaced with a different, proper interchange or bypassed by thru traffic via flyover ramps built over the roundabout.
