interests, has made it possible for the state to build many new miles of roadway throughout the state. As part of this program, US 231 is currently being updated to a new-terrain four-lane highway from the Indiana-Kentucky border through Spencer County to Interstate 64. This segment of US 231 has been named the Abraham Lincoln Memorial Parkway. As of April 2011, the Lincoln Parkway is complete from the Kentucky line to the interchange at I-64 and the bypass of Dale at the northernmost end of the project. It is a fully operational partial cloverleaf and the previous two-lane 231 overpass has been demolished. It has been replaced by a new four-lane overpass. The section from SR 162 to Indiana State Highway 70 near Chrisney was the last to be opened, after a ribbon-cutting ceremony on March 15, 2011, much sooner than the original July 2011 projected date. In addition to the Spencer County project, a four-lane bypass of the Dubois County cities of Huntingburg and Jasper is also in the planning stages, but funding has not been secured. A firm timetable for construction has yet to materialize. History U.S. Route 152 was commissioned in 1934, connecting Indianapolis with Hammond. It followed US 52 from Indianapolis to northwest of Lafayette, where it turned north to end at US 20 in Hammond. In 1938, the route was decommissioned, and became a southern extension of State Road 53 from northwest of Lafayette to Crown Point, a new State Road 152 from Highland to Hammond, and was simply dropped in favor of the overlapping US 52, State Road 8, and US 41 elsewhere. These parts of SR 53 and SR 8 became US 231 in 1952, when US 231 was extended north from Montgomery to US 41 south of St. John.
