only between the US 44 and northern NY 82 exits. The changes in the design of the northern Taconic also reflect higher speeds that mid-century automobiles were capable of, and improvements in construction technology. The track-equipped steam shovels that broke ground for the first section in Putnam County in 1931 were the most advanced excavators of the time. Over the next decade, the cost of moving a cubic yard dropped to almost half of what it had been in the early 1920s. Later in the parkway's development, engineers began using aerial photographs to plan the route. The road's drainage system had some special features designed to avoid detracting from its scenic qualities. The roadway was crowned, with storm drain grates at the edge since there was no shoulder, to keep water from forming deep puddles that could cause accidents (these have been eliminated from modernized sections of the parkway in Westchester). The soft hand-fluted curbs also helped channel runoff to the basins, and in the median strips a central trench took water to underground pipes which drain into local streams. The median strips themselves were not part of the original design on the lower sections of the Taconic, save for sections like Fahnestock State Park where designers used them to enhance the scenic capabilities of the road and create recreational opportunities. As the road was extended north during the 1930s, it became clear that the wider medians improved safety without sacrificing beauty, and starting with the NY 52 exit in East Fishkill they were made a standard element of the parkway's design. Wider medians were also a lot easier to build in Dutchess and Columbia counties, as the land is much flatter than in Putnam County. When the parkway was modernized and widened in Westchester County, wide medians were installed for most of the length between the Sprain Brook Parkway and the Putnam County line. History The Taconic came into being as a result due to the increasing presence of the automobile in American society and the demand for more public parks near crowded cities. Two separate agencies, the Taconic State Park Commission (TSPC) and Westchester County Parks Commission (WCPC), were its initial constructors, building different segments. In time a state authority would take over from them both, and then 18 years later itself yield up to its current administrator, the state Department of Transportation. It would take nearly four
