for the Ypsilanti bypass. In 1963, the freeway was extended south of New Buffalo to end at M-239. Traffic was diverted down M-239 into Indiana where State Road 39 carried traffic the rest of the way to the Indiana Toll Road. By the end of the year, a section of highway opened between Mount Clemens and Marysville, and US 25 was rerouted to run concurrently along the freeway from the New Baltimore area northward. The eastern terminus of I-94 in the Port Huron area was dedicated on October 14, 1964, signaling the completion of the highway between Marysville and the Blue Water Bridge. This completion displaced part of the M-146 bypass of Port Huron, the southern leg of which was retained as a connector to present-day Lapeer Road. Two years later, the gap between the Wayne–Macomb county line and the end of the freeway near Mount Clemens was filled in when another section of freeway opened. In late 1964, a plan was approved to improve the interchange with Telegraph Road (US 24), as the original interchange did not feature access in all directions. North of Albion, the route of the freeway previously crossed a branch of the New York Central Railroad at-grade; the crossing was eliminated when the tracks were removed in 1968. The sections originally designated as the Willow Run Expressway were rebuilt from Rawsonville Road in Belleville to Ozga Road in Romulus starting in 1972. As part of this reconstruction, the segment between Haggerty and Ozga roads was widened from four to six lanes, and the eastbound lanes were realigned to facilitate construction of an interchange with I-275, a western bypass of Detroit which was under construction at the time. The Willow Run segment was also resurfaced at this point, as the old road bed did not contain steel mesh. Construction of this interchange also obliterated a partial interchange with Huron River Drive. The final section of I-94 in Michigan opened to traffic on November 2, 1972, when the connection across the state line into Indiana was dedicated. This last segment in Michigan between M-239 and the state line opened when Indiana completed an segment of freeway in their state. Since completion The interchange with the Southfield Freeway (M-39) was closed entirely in 1985 to replace the original exit design, which included four on-ramps that sharply merged into the left lanes of I-94. Reconstruction added new on-ramps that
