The Boston-based designer has been approached by Birmingham City Council to head up the transformation of the infamous motorway intersection.
It is understood that the council wants the junction - officially known as the Gravelly Hill Interchange - to become a landmark gateway for Birmingham.
However, details of the scheme remain firmly under wraps because of Living Landmarks Lottery Fund rules which prevent publication of potential projects. The council hopes to receive a substantial grant from the lottery to fund the proposed overhaul of the junction, which was opened in 1972.
The convergence of the M6 motorway and A38(M) Aston Expressway, the junction spans the rivers Tame and Rea and a number of key railway lines.
