^Because that wouldn't have made sense in terms of the whole project. You can't do one corner of an interchange when the roads themselves are also being widened. You would have to come back and redo the ramps that you created in the first phase. The first phase of this project that has already been completed involved widening both I44 and US75 through the interchange. Now the ramps have a place to go, and they've already been halfway constructed.

This interchange has suffered from major rush hour backups for as long as I've lived in the area. It's been a source of constant wrecks that mess up the morning commutes to downtown from the south suburbs. We have a couple others that are way beyond capacity for cloverleaf style interchanges.

240/35 in OKC should also be a priority. IMO, the state should be focused on upgrading cloverleafs in both major metros for the next decade.
