State Road 39

Measuring 20.53 miles in length, State Road 39 is an arterial route from SR 60 in northeastern Hillsborough County to U.S. 301 (Gall Boulevard) in southeastern Pasco County. Traversing rural areas north from SR 60 and Hopewell, SR 39 runs along James L. Redman Parkway to Trapnell Road at the Plant City line. Becoming a commercial arterial, James L. Redman Parkway leads SR 39 north to Alexander Street.

Prior to 2013, SR 39 remained along James L. Redman Parkway north onto Collins Street to Downtown Plant City. The state road shared a two block concurrency with U.S. 92 along the couplet of Baker Street west and Reynolds Street east to connect with Wheeler Street. SR 39 continued along Wheeler Street north to a folded diamond interchange with Interstate 4, where Paul S Buchman Highway took over north to Knights.

State Road 39A was the previous designation for Alexander Street from James L. Redmon Parkway to Interstate 4 on the west side of Plant City. The truck bypass was incorporated into a realignment of State Road 39 following the completion of the 2.7 mile long extension of North Alexander Street on December 23, 2013. The former route of SR 39 along Paul S. Buchman Highway southeast to I-4 was redesignated as CR 39. This changed in 2017 when CR 39 was renumbered as a new branch of SR 39A. Wheeler Street 1.17 miles south to U.S. 92 in Downtown became an unsigned branch of CR 39.

SR 39 continues from N Alexander Street on Paul S. Buchman Highway to Knights, Moriczsville and Crystal Springs in Pasco County. The state road converges with U.S. 301 on the south side of Zephyrhills.
