1970 map of proposed route of I-485 through northeast Atlanta
|Auxiliary route of I-85|
|Length||5.9 mi (9.5 km)|
The 5.9-mile-long (9.5 km) route would have begun at the Downtown Connector (I-75/I-85) and used the proposed State Route 410 (SR 410) east to the interchange with the also-proposed SR 400. There, it would have turned north to end at I-85 near Lindbergh Drive (SR 236). Each of those freeways would have continued beyond the termini of I-485. SR 410, the Stone Mountain Freeway, would continue east beyond the I-285 perimeter highway, and SR 400 would extend both south and north outside the perimeter. A short piece of I-485/SR 410 was constructed from I-75/I-85 east to Boulevard NE.
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.
