State Road 4 in the U.S. State of Indiana refers to three separate disconnected surface highways in northern Indiana, although local highways that have never been part of the state highway system could in fact connect them.
The western segment is the longest of the three at 25 miles (40 km). This segment begins at LaPorte at State Road 2. It crosses State Road 23 in North Liberty and has a short spur, State Road 104. It ends in Lakeville where it meets U.S. Route 31.
This segment will be extended eastward along Pierce Road to connect with a new alignment of U.S. 31 which is under construction as of 2011.
The central segment is 7 miles (11 km) long and is the original section, completed in 1926. The western terminus is at State Road 15/U.S. Route 33 in Goshen. The eastern terminus is at State Road 13 in Elkhart County.
The eastern segment is the shortest of the three at 6 miles (9.7 km). Much of this segment used to be designated as State Road 727 until U.S. Route 27 was re-routed onto the newly completed Interstate 69. The western terminus is at Indiana State Road 327 in Helmer, and the eastern terminus is at an interchange with Interstate 69 in Ashley. It runs parallel with an Indiana Northeastern Railroad line, which is just 1,000 feet (300 m) to the north of the highway.
