It's at this intersection where SR 39 makes a left turn while James L. Redman Parkway continues as State Road 39A.

The next major intersection is the northern terminus of State Road 39A, which is named Paul S. Buchman Highway.

After passing by the Blackwater Ultralight Flightpath, SR 39 and the Yeoman Subdivision both run near a mine just south of the Hillsborough-Pasco County Line.

In Crystal Springs the road moves away from the Yeoman Subdivision in south of the Hillsborough River, but still remains at a northwesterly direction.

Just north of the river, it gradually enters Zephyrhills South where the first major intersection is County Road 535.

After the intersection with Dr. Martin Luther King Jr. Boulevard, it crosses the CSX Lakeland Subdivision, which carries Amtrak's Silver Star line, and enters the Downtown Plant City Commercial District where two blocks later intersects eastbound U.S. Route 92 (State Road 600/State Road 574).

From here it enters the Downtown Plant City Historic Residential District which ends just south of the interchange with Interstate 4 (Exit 21), which also contains frontage roads that serve SR 39.

North of the interchange with I-4, much of SR 39A runs along the west side of the Yeoman Subdivision as it becomes the Paul S. Buchman Highway.

It then broke away from US 98/SR 50 and was the designation for Croom-Rital Road, a street which runs along what today is the Withlacoochee State Trail, until reaching the unincorporated hamlet of Croom.

[4] North of Floral City, former SR 39 runs along Old Floral City Avenue, where it runs along the Withlacoochee State Trail past County Road 39A, and Fort Cooper State Park, before entering Inverness South.

This route was officially eliminated when Alexander Street was extended to Paul Buckman Highway in Knights, and SRs 39 and 39A switched places within Plant City.

SRs 553 and east Truck Route 39 end at the interchange with Interstate 4 (Exit 22), which also contains frontage roads that serve SR 39.

In the early 20th century, a connection between County Road 48 and SR 200 was planned to run along the west-north side of the Withlacoochee River.
