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 49
The 180-mile (289.7 km) section between Texarkana and Fort Smith remains largely incomplete. Right-of-way has been acquired and engineering has been completed, but construction is contingent upon allocating funding to the corridor. After applying for and receiving assistance from the 2012 Transportation Investment Generating Economic Recovery (TIGER) grant program, ArDot has begun construction on a new highway location for I-49 between the current I-40/I-540 interchange and US 71 south of Fort Smith, bypassing Van Buren and Fort Smith. Work is now complete between US 71 and Highway 22 near Fort Chaffee as the first and southernmost phase of the extension of I-49 south of I-540. The project is explicitly mentioned as an effort to complete I-49 in the TIGER grant application. Colloquially referred to as "Chaffee Crossing", this first phase was completed on July 15, 2015 at 10:00am at the AR-549 and AR-22 Interchange. I-49 is planned to follow the general route of US 71 through the state between Interstates 30 and 40.
