The east end of the 1979 ROW transfer west of I-75 was at the limited access ROW line, which was 349.94 feet east of the section line (CR 491) and 472.24 feet west of the centerline of I-75. It appears that this is about 30 feet east of CR 495, which is presumably close enough to use CR 495 as the west end.
The west end of the 1978 ROW transfer east of I-75 was at the east edge of the railroad ROW. Being about 250 feet east of CR 475, this should probably get an End point.
I can't determine if there were any changes during the recent widening of I-75.
I can send you the files if desired.
