U.S. 280 in Birmingham and Shelby County to get traffic signals designed to aid flow:

So only the toll part will be elevated, while the rest remains at-grade? This strikes me as strange, especially the part that is not limited-access. All said, I don't think tolling US 280 is the way to go, although it certainly could use an upgrade in that area.
