sites, the Don Shula Expressway swings north over the railroad, crossing over Galloway Road (SR 973) in the process, and resumes its northeasterly orientation, now forming the boundary between the communities of Olympia Heights, to the road's north, and Glenvar Heights, to the south. later, SR 874 passes through its third and final toll gantry, before reaching its northern terminus in a partial interchange with the Palmetto Expressway after another . Like at its southern terminus, SR 874 forms the central lanes of SR 826 northbound; however, its interchange is integrated with SR 826's interchange with Bird Road (SR 976). Also like its southern terminus, there is no access for northbound SR 874 or SR 826 traffic to the other route's southbound counterpart. Tolls SR 874's tolls are entirely electronic: cash cannot be accepted along its length. Payment is done either via SunPass transponders or via toll-by-plate billing, the latter of which attracts a higher cost. Three toll gantries are located along the Don Shula Expressway: the first between the HEFT and Killian Parkway, the second between Killian Parkway and Kendall Drive, and the last between the Snapper Creek and Palmetto Expressways. The relationship between the tolling points and interchanges along SR 874 and SR 878 is that all motorists are charged at least one toll for using the road; there are no "free sections". As of July 1, 2013, the cost for a two-axled vehicle to drive the entire length of SR 874 is $1.00 with a SunPass transponder, or $2.00 via the toll-by-plate program, with the two southern gantries charging $0.25 (SunPass) or $0.50 (toll-by-plate) each, and the northern one charging twice as much. Each additional axle on a vehicle attracts a surcharge equal to the cost of a two-axled vehicle for each gantry passed. History The history of the Don Shula Expressway can be traced back to 1957 when, in planning for the Palmetto Expressway's routing, Dade County Commissioner Ralph Fossey proposed an alternative southern alignment of the expressway to follow the then Seaboard-owned railroad southwest from near Miller Drive (Southwest 56th Street) to Southwest 117th Avenue, before heading south to US 1 at Goulds, instead of heading due south to Kendall. While the Palmetto Expressway was built to its original plan in 1961, the concept of an expressway next to the Seaboard tracks south of Miller Drive, termed the South Dade Expressway, continued to feature in
