Indiana 25 exists in two segments along a southwest to northeast path across north central Indiana for a total of distance of 123 miles. The western segment begins at Indiana 32 near Waynetown in Montgomery County and runs north toward the Lafayette area and ending at the intersection of U.S. 52 & 231. The highway used to follow Teal Road, Sagamore Parkway and Schuyler Avenue around the city of Lafayette before meeting up with the now-eastern segment of the highway at Interstate 65. As of September 13, 2013 that is no longer the case as INDOT decommissioned that stretch of highway when U.S. 52 was routed off of Sagamore Parkway and onto Teal Road and all roadways other than U.S. 52 and U.S. 231 were given back to Lafayette. This has created a gap in the highway, that has best typified the INDOTs policy on decommissioning highways without providing an alternative route, for those traveling from northeast to southwest and vice versa.

From Lafayette, it heads northeast toward Delphi and Logansport along the Hoosier Heartland Corridor, a new four-lane expressway that carries some characteristics of a freeway with limited at-grade crossings and two new interchanges at Delphi and Logansport. From Logansport, the highway continues north and northeast through Rochester before ending in the Kosciusko County seat of Warsaw. The middle stretch of the highway from Lafayette to Logansport is an important trade corridor, part of a larger corridor between Layette and Fort Wayne, and for these reasons it is (and will) be expanded to four lanes. On October 24, 2012 the segment from Interstate 65 in Lafayette to U.S. 421, Indiana 18 & 39 in Delphi was opened. The remainder segment from Delphi north to U.S. 24 & 35 opened October 18, 2013.

Indiana 25 previously followed Main Street town before being rerouted onto the Hoosier Heartland Highway along a bypass to the south and east. U.S. 421, Indiana 18 & 39 still follow Washington Street and Main Street west town. Note the cutout shield for U.S. 421, one of a few posted in Delphi. Photo taken 12/28/11.|
