Initially, the freeway had several at-grade intersections with crossroads: Hanley and Latcha roads near Perrysburg; Ayers, Lemoyne, and Walbridge roads near Walbridge; and Curtice Road in Northwood. The Walbridge intersection was later upgraded to a traffic signal, one of the few on the Interstate Highway System at the time, while the intersection underwent study for conversion to an interchange. Hanley and Latcha roads were truncated to dead-end just before the freeway, but access to both roads was retained by construction of a new interchange and service drives in the early 1970s; the Ayers and Lemoyne crossings were also upgraded to overpasses at this point. The removal of direct access to Hanley and Latcha was originally disputed by business owners who owned motels and gas stations along those roads. The crossing at Curtice Road was upgraded to an interchange concurrently with the upgrade of the nearby interchange with Woodville Road.
