The northern segment follows an old alignment of Dixie Highway from CR 723 in Stuart to SR A1A in downtown Fort Pierce.
This segment is also known as Dixie Highway and Indian River Drive and runs parallel to the Florida East Coast Railroad tracks from Fort Pierce to Jensen Beach.
In the 1990s, the Florida Department of Transportation removed the State Road from several routes in the Stuart area, including SR 707A.
(see image at left) A FDOT-published county map from February 2002 listed the road as solely CR 732.
Shopping centers are clustered near its interchange with Jensen Beach Boulevard while business and industrial parks straddle the county road near its southern terminus.
