MDSRC purchased the Frederick and Emmitsburg Turnpike from its operating company in 1911. The first section of the turnpike to be rebuilt as a modern road was between Tuscarora Creek north of Frederick and just north of Sundays Lane near Hansonville in 1911. The old turnpike was resurfaced as a macadam road from Lewistown to Thurmont in 1914 and from Harmony Grove to Lewistown in 1915. The Gettysburg Road from Emmitsburg to the Pennsylvania state line was also paved in 1915. The gaps between Thurmont and Emmitsburg and between the city of Frederick and Harmony Grove were resurfaced between 1915 and 1919; the Frederick – Harmony Grove road followed the turnpike right-of-way north from Worman's Mill rather than the 1910 planned route via Pike.
