The Spadina subway line was built in the median of the project right-of-way from Wilson to Eglinton. The route south of Eglinton follows the approximate route planned for later sections of the expressway, albeit underground. During the planning of the route, alternate routes directly south along Christie Street and south along Bathurst Street were also considered. After the use of the University section of the subway by Bloor–Danforth trains was abandoned, the original route of the subway to connect with the St. George station was agreed upon. The University section of the Yonge line was made into a part-time route until the Spadina subway extension was built. After the cancellation of the Expressway in 1971, the subway's construction had not been started. Route studies occurred again, the original route was confirmed once more, and it proceeded to construction. It opened in 1978.
