As initially envisioned, the Hanlon Expressway will be upgraded to a controlled-access highway by removing all existing at-grade intersections and improving the highway to 400-series standards. Planning for this work initially began in the early 1990s with the EA for the section north of the Speed River, which resulted in the construction of the Wellington Street interchange. The EA for the section south of the Speed River began in early 2007. The Laird Road interchange and associated closing of the Clair Road intersection were the first projects completed as part of this work.
