for I-459 Negotiations between the Alabama Department of Transportation (ALDOT) and the city of Hoover are continuing regarding the prospective building of an additional interchange for I-459 at South Shades Crest Road, a heavily traveled traffic artery. An exit here would relieve some of the traffic congestion on SR 150. No firm plans have been announced for construction of this interchange. Northern bypass There are plans to construct another Interstate Highway bypass running north of the Birmingham area to provide another Interstate Highway that would have major interchanges with I-59 (two), I-20 (one), I-65 (one), and the newly constructed I-22, with all of these interchanges being either north or west of Birmingham. This new bypass route has been tentatively numbered as Interstate 422. When this northern bypass of the urban area is built, it would give Birmingham and Jefferson County a completely ringed Interstate bypass.
