The corridor — Dixie Way

Roseland is a corridor town, and its spine is the road. The road through it is the Dixie Highway line, Indiana's north–south Dixie route from the Michigan line through South Bend — carried in the state system as State Road 1 from 1917 and renumbered U.S. 31 in 1926 (with U.S. 33 concurrent north of Sample Street from 1 January 1938); its Roseland segment is named Dixie Way in the town's current addressing (North and South Dixie Way).Michigan Road does not touch Roseland — in South Bend it ran on Michigan and Water streets and joins the later highway corridor only downtown; the U.S. 31/Michigan Road overlap lies south of the city. What runs through Roseland is the Dixie Highway line, not the 1830s state road. In the 1970s the St. Joseph Valley Parkway took the through routes around South Bend on new alignment west of the city — its Toll Road interchange (Exit 72) built from 1979 and opened on 27 October 1980 — and the Roseland alignment became the business route. The designation change on this segment is settled, by decomposition, in the corridors file (C5, rl-rd-bypass): the parkway’s Bypass U.S. 20 designation was replaced by U.S. 31 in 1978; the northern freeway was completed and opened in 1979–80, its Michigan section dedicated 10 August 1979 and the Toll Road interchange opened 27 October 1980; and through traffic actually left this corridor in 1982, when the new U.S. 31 was completed and Business U.S. 31 was created on the old alignment. The old alignment through town today is State Road 933, coined in April 1998 — the state removed U.S. 33 north of U.S. 20 (AASHTO approval, 25 April 1997) and, St. Joseph County having refused the road’s transfer, the orphaned segment took the 933 number (rl-rd-sr933); it passes under the Toll Road in Roseland, runs north to the state line where it continues as Michigan's M-51, and southbound passes between Notre Dame on its east and Holy Cross College and Saint Mary's College on its west.
