Despite DuPont's grand boulevard not coming to fruition, he was a visionary who implemented key practices before they became standard in the decades after he initiated his project. After his death in 1930, DuPont was recognized for foreseeing that traffic on highways would approach the speed and volume of railroads and planning with provisions for future needs. Based on that vision, he designed his highway with a wide right-of-way and curves and grades adequate for high-speed traffic. The DuPont Highway was also innovative as one of the earliest roads to be constructed on a new alignment that passed close to towns but not directly through them, a development that was more convenient for through traffic and less disruptive to a town's residents. Up to that point, the use of bypasses had been limited to the railroads. South of Milford, the DuPont Highway was constructed entirely on new alignment except from Bedford Street north of Georgetown to Old State Road at Redden. The portion of the highway north of Milford, which DSHD designed, mostly overlaid the existing Milford–Dover highway. The two exceptions were through Frederica, where the State Road used Market Street, and between Milford and Frederica, where the State Road followed Jenkins Pond Road, Reynolds Road, Pritchett Road, and Milford Neck Road.
