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 270 (Colorado)
Construction on I-270 began in 1965. The first portion cost about $2.7 million. It opened in 1968, connecting I-70 to Vasquez Boulevard. Two years later, another two-mile (3.2 km) segment connected the portion already in service to I-80S. I-80S became I-76 in 1976. Construction began on the section between I-76 and I-25 in April 1993 and was finished in September 1999, costing $11.4 million. The mileposts were already established when construction took place, so the route was not assigned new mileposts. Completion of this portion largely decreased traffic problems in the area.
