In greater Miami, the Miami-Dade Expressway Authority and Florida's Turnpike Enterprise (FTE) maintain eight state expressways in conjunction with FDOT. The Airport Expressway (SR 112) and the Dolphin Expressway (SR 836) relay western Miami-Dade suburbs to the eastern urban coast at I-95, and to Miami Beach via I-195 and I-395 at the Airport and Midtown interchanges. The Gratigny Parkway (SR 924) connects northern Miami suburbs to the southern end of I-75. The Palmetto Expressway (SR 826) is the primary beltway road of urban Miami, relaying I-95 and Florida's Turnpike (SR 91) at the Golden Glades Interchange near northeastern North Miami Beach to the southern inland suburbs of Kendall and Pinecrest. The Don Shula Expressway (SR 874) and the Homestead Extension of Florida's Turnpike (SR 821) form the southernmost end of the beltway, connecting the Palmetto Expressway to the bedroom communities of Homestead and Florida City. The Snapper Creek Expressway (SR 878) relays the Don Shula Expressway to South Dixie Highway (US 1).
