Activists in the neighborhood of Morningside, along the SR 400 portion of I-485, were the first to fight the road, although opposition surfaced in a number of nearby surrounding neighborhoods. After I-485, and parts of SR 400 and SR 410, was canceled, a portion of the right-of-way was used to build Freedom Parkway, now part of SR 10. SR 400 north of I-85 was constructed in the early 1990s as a toll road, and the section south of I-285 was constructed in the mid-1980s and designated Interstate 675.
