State Road 874 (SR 874), named the South Miami Dade Don Shula Expressway for its length, is an electronic toll road in southern Miami-Dade County, Florida. It extends northeast from the Homestead Extension of Florida's Turnpike (HEFT) in southwestern Kendall to SR 826 (Palmetto Expressway) in Glenvar Heights, allowing traffic from the far south of Miami-Dade County and the Florida Keys to move to more central regions of metropolitan Miami and vice versa, bypassing communities along US 1, while also permitting local access to the Kendall district. The road, named in honor of the long-serving coach of the Miami Dolphins NFL team, is maintained and tolled by the Miami-Dade Expressway Authority (MDX). Contrary to the numbering plan of Florida State Roads, SR 874 is signed north–south. Route description SR 874 begins at an interchange with the HEFT on the boundary of the communities of Three Lakes, Richmond Heights and Kendall, about southwest of Downtown Miami. The expressway is formed from the median lanes of the HEFT, and immediately turns to the northeast, passing under the HEFT's northbound lanes. Southbound HEFT traffic cannot access northbound SR 874; likewise, southbound SR 874 traffic cannot access the HEFT northbound. After turning to the northeast and entering Kendall, the six-laned Don Shula Expressway subsequently parallels CSX's Homestead Subdivision past predominantly residential neighborhoods for its entire route. SR 874 meets its first of three toll gantries about north of its southern terminus, just north of its former lone toll plaza. About from SR 874's southern terminus, the expressway interchanges with Killian Parkway (SR 990) and Southwest 107th Avenue (SR 985) at a partial cloverleaf interchange. The Don Shula Expressway continues on for , passing through another toll gantry, before reaching an interchange with Kendall Drive (SR 94). Almost immediately afterwards, SR 874 crosses the Snapper Creek Canal and enters the Sunset district. It then reaches the partial interchange with the Snapper Creek Expressway (SR 878); indeed, southbound motorists along the Don Shula Expressway who wish to exit to Kendall Drive are directed onto the westernmost portion of SR 878. Once past the Snapper Creek Expressway, SR 874 features no interchanges for the remainder of its route. Just north of the bridge over Sunset Drive (SR 986), about north of SR 878, motorists in both directions are provided with a separated lane to take their vehicles to if caught in an accident. past the accident investigation
