Interstate 69 in Indiana
The original plan (in a DEIS prepared by INDOT in 2004, but later dropped) was for I-69 to leave the now-former I-164 alignment somewhere just east of Green River Road (exit 3) and head south (instead of turning west with I-164) for approximately before crossing the Ohio at a point near the mouth of the Green River. This portion of the route had not then been funded, as construction of the new Ohio River crossing and its approaches in both states was expected to cost approximately $800 million. Indiana and Kentucky officials had said construction on the new Ohio River Bridge would not begin until at least 2020, after two new crossings near Louisville were completed. With Indiana then preparing to break ground on SIU 3, Kentucky officials indicated that collecting tolls might be the only feasible option for completing the I-69 bridge, as traditional federal and state funding for such projects were drying up. , neither Kentucky nor Indiana officials had yet come up with the money to plan and construct this I-69 bridge.
Interstate 696
Planning for the freeway started in the 1950s. Michigan state officials proposed the designation I-98, but this was not approved. Construction started on the first segment in 1961, and the Lodge Freeway was designated Business Spur Interstate 696 (BS I-696) the following year. The western third of the freeway opened in 1963, and the eastern third was completed in January 1979. The central segment was the subject of much controversy during the 1960s and 1970s. Various municipalities along this stretch argued over the routing of the freeway such that the governor locked several officials into a room overnight until they would agree to a routing. Later, various groups used federal environmental regulations to force changes to the freeway. The Orthodox Jewish community in Oak Park was concerned about pedestrian access across the freeway; I-696 was built with a set of parks on overpasses to accommodate their needs. The Detroit Zoo and the City of Detroit also fought components of the freeway design. These concessions delayed the completion of I-696 until December 15, 1989. Since completion, the speed limit was raised from . In addition, some interchanges were reconfigured in 2006.
