In 1938, US 152 was decommissioned, and for the next 14 years its former route between St. John and Montmorenci carried state highway designations. But in 1952, the US 231 designation was extended north from Alabama, and its northernmost segment was routed along historic US 152, ending in St. John: |
For much of that time, the highway did not junction US 41 at a standard four-way intersection (like it does today). Instead, just east of US 41, the highway curved to the north and met US 41 at an angle: | That angled segment was vacated sometime in the 1980s, but part of it is still visible on the left side of this interactive image: The north beginning of US 152 was to the left. Later the same was true of US 231, but now the north beginning of that designation is just a bit further south on US 41. |
