The Oklahoma Department of Transportation stated they created the roundabout design with 10 road connections after pulling what they said was a similar design they found on the Facebook page for Friends for a Better Boulevard, the advocacy group arguing to keep the road at-grade instead of elevated as sought out by the state highway engineers. The advocacy group responds they did not have a rendering even close to the one released by ODOT. I looked at all the images on the Facebook page and did not see any with 10 road connections.
On Oklahoma river development:
Guest, we're seeing this sort of development along the river by Meridian Avenue and SW 15 currently. As for the river as it flows south of downtown, I suspect it's just a mater of a few more years, if that, before we start hearing such announcements. I suspect that developers are awaiting further development to occur first in Core to Shore.
On Bricktown housing:
Bricktown has long shown great capacity for housing - the trick is overcoming land costs and parking arrangements. The U-Haul building, I agree, would make for the best historic building housing rehab project anywhere in the city. Small problem - U-haul doesn't seem to want to move.
