In 1924, Dixie Highway was paved from Pontiac to Flint. With the decline of agriculture as a major economic activity in the township, residents began commuting to Pontiac and Flint for employment in the developing automotive factories, marking the beginning of the township's decline. By 1930, Springfield Township's population had fallen to 923. The township's decline would unexpectedly be reversed in the 1960s with the construction of Interstate 75. The accessibility provided by two interchanges accelerated residential growth in the late 1960s and 1970s. Population improved, going from 1,825 in 1950 to 2,664 in 1960, 4,388 in 1970, 6,502 in 1976, and 8,295 in 1980.
