The LaSalle Expressway (reference route 951A) was planned as part of the Belt Expressway, an outer loop around Buffalo; the only other part constructed was the Mile Strip Expressway on NY 179. The stub interchange at its eastern end is a hint of these plans. The route was also planned to extend west to the Rainbow Bridge.
