. Between then-SR 402 and SR 520, SR 3 was cosigned with SR A1A.

The openings of the Emory L. Bennett Causeway and the Pineda Causeway (in 1971) triggered a massive transformation of SR 3. The former causeway shifted SR A1A to the north (to the newly-extended Bee Line Expressway) as SR 3 was realigned to cover North Courtenay Parkway and provide the access to the Kennedy Space Center (the segment north of KSC lost its SR 3 and A1A signs); the latter causeway prompted the establishment of South Patrick Drive as the primary southern access to Patrick Air Force Base

added a "C-" prefix to the signs on the stretch south of SR 520 and started the transition from State Road 3 to Brevard County Road 3 -- yet a handful of "State Road C-3" signs are still posted on Tropical Trail near the southern tip of Merritt Island.

Courtenay Parkway eventually was extended past the SR-520 beyond the Merritt Island Airport to the historic community of Georgianna, where it meets up with the older South Tropical Trail, however this is a county facility and does not carry the state road designation. The last phase was completed in the late 1980s.
