State Road 4 (SR 4) is an east–west discontinuous state road in the US state of Indiana. The western end of the western segment is in La Porte. The highway passes through rural areas of LaPorte and St. Joseph counties, before ending near Lakeville. The central segment starts at the eastern city limits of Goshen and heads east passing through rural Elkhart County, before ending at SR 13. The eastern segment runs between SR 327 and Interstate 69 (I-69), passing through the towns of Ashley. The state road runs through five counties in northern Indiana mostly through rural farm fields and small towns.
Dating back to the early days of the state road system, SR 4 was first signed in the southern part of the state. It was moved to its modern routing in 1932, running from Goshen to SR 13. In the early to mid 1940s, SR 4 was added to the state road system between La Porte and Lakeville, while the eastern segment was added in the late 1940s, running from SR 327 to U.S. Highway 27 (US 27). The segment of roadway east of I-69 was removed from the state road system in the early 1970s. In the mid-2010s the western segment of roadway was extended east to meet the new alignment of US 31 and the western end of the central segment was moved from downtown Goshen to the eastern city limits.
