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 93
These new roadways were built during a twelve-year period from 1994 to early 2006. The massive project became the largest urban construction project ever undertaken in American history. Construction on the new I-93 segment was not without serious issues: a lengthy Federal environmental review pushed the start of construction back from approximately 1990, causing many inflationary increases; funding for the project was the subject of several political battles between Pres. Ronald Reagan and Rep. Thomas P. O'Neill, Jr. Major construction on the new roadway was done while maintaining the old roadway, a step that also greatly increased the cost of the project. The original Charles River crossing, named Scheme Z, was the object to great public outcry similar to that of the building of the original highway. The outcry eventually led to the replacement of Scheme Z with a newer, more sleek cable-stayed bridge and complementing exit for Cambridge, increasing the cost even more.
