The expressway's construction plans provided a dedicated right-of-way for trains in the highway's median strip. However, during the estimated five years to complete the superhighway, both "L" and interurban trains would need to use a temporary street-level right-of-way. When the plans circulated in 1951, CA&E objected to the arrangement, citing the effects on running time and scheduling of its trains as they negotiated the streets of Chicago's busy West Side at rush hour. The railroad estimated that the delays would cost the railroad nearly a million dollars a year, to say nothing of the long-term effects of the new superhighway on the railroad's revenue. Another long-term concern was the railroad's downtown terminal; the new median strip line would have no access to Wells Street Terminal.
