State Road 434 (SR 434) is a major roadway in the Central Florida area.

SR 434 is called Central Avenue when it first turns south towards downtown Oviedo.

After going through downtown Oviedo, SR 434 is called Alafaya Trail from its intersection with Mitchell Hammock Road south to the Orange County line to its end at SR 50 (Colonial Drive).

Alafaya Trail continues south of Colonial Drive without the SR 434 designation.

[2] On June 2, 2018, a section of SR 434 in Oviedo was closed after an old drainage structure below the road collapsed and caused a 3-foot (0.91 m) wide hole to open up.
