State Road 924 (SR 924) is an east–west highway connecting I-75 and SR 826 (Palmetto Expressway) in Hialeah and SR 909 (West Dixie Highway) in North Miami. The westernmost 4.85 miles (west of West 32nd Avenue), named the Gratigny Parkway (or simply, the Gratigny), is a limited access all-electronic toll road maintained by the Miami-Dade Expressway Authority (totalling to two gantries of $0.47 each for SunPass users and $0.94 each for toll-by-plate users); the easternmost is a surface street (Northwest 119th Street) also known as Gratigny Road. Despite its relatively short length, SR 924 is a major east–west artery in northern Miami-Dade County. Route description The road begins at the national southern terminus of Interstate 75 at the Palmetto Expressway at the border between Miami Lakes and Hialeah. The road heads east as an eight lane expressway through Hialeah's residential areas and through the first of two $0.47 toll gantries ($0.94 for toll-by-plate users). Following the gantry, the expressway has its first interchange with NW 57th Avenue/Red Road, giving access to Opa-locka Airport just north of the toll road. SR 924 then curves southeast, leaving Hialeah and heading towards the second $.47 toll gantry ($0.94 for toll-by-plate users) in Opa-locka, followed by an interchange with SR 953 before the expressway ends at NW 32nd Avenue, becoming NW 119th Street, a divided surface street heading due east. The road then becomes a mix of commercial and residential areas as it crosses SR 9, then reaching North Miami, intersecting with U.S. Route 441/SR 7, followed by Interstate 95, becoming a residential street before ending at SR 909. Tolls The tolls on the expressway portion of SR 924 are all electronic, and does not accept cash. Payment is done either via SunPass transponders or via toll-by-plate billing, the latter of which attracts a higher cost. Two toll gantries are located along the expressway portion of the road, each charging $0.47 for SunPass users and $0.94 for Toll By Plate users. The eastern toll gantry is placed at the location of the former toll plaza which closed in 2010 when cash collection ended. As of June 8, 2018, it costs $0.94 to travel the entire expressway portion via SunPass and $1.88 via Toll By Plate. All motorists are charged at least one toll for using the road; there are no "free sections" as existed prior to the electronic toll conversion in 2010. History Despite
