State Road 934 is, for its longest span, Northwest 79th Street in Miami, but also traverses a variety of names as it crosses Hialeah Gardens, Hialeah, North Bay Village, and Miami Beach as Northeast 74th Street, the Hialeah Expressway and 21st Street in Hialeah, as the North 79th/81st Street one-way pair in Miami, the John F. Kennedy Causeway as it crosses Biscayne Bay, and as Normandy Drive and 71st Street in North Beach, Miami Beach (the last two forming a one-way pair in Miami Beach, respectively).

About two blocks east of the expressway, it crosses Milam Dairy Road/West 72nd Avenue, becoming the Hialeah Expressway, a limited access stretch of highway that extends to US 27 (SR 25), and ends at Red Road (West 4th Avenue, SR 823).

The expressway, however, does not have any complete interchanges; it is made up of at-grade intersections at each end of the expressway and between them, they consist of a single westbound off ramp onto North 74th Street near West 69th Avenue, a half diamond with US 27 and an at-grade intersection with West 12th Avenue.

Signage along Hialeah Expressway is minimal as only the westbound off ramp onto US 27 (Okeechobee Road) has a sign with the destination street on it.

After intersecting US 1/SR 5, the roads rejoin just west of the western end of Biscayne Bay and the John F. Kennedy Causeway.
