US 431 and US 41 have had different routes through Springfield. US 41 formerly had a more eastern route, now called Old Greenbrier Road. A portion of the old route was abandoned in the 1990s due to landscaping made during the construction of a railroad. The practical usage of the road was replaced by the 17th Avenue Connector. The old pavement is still visible from Bill Jones Industrial Drive. Beyond that, it ran more westerly through downtown Springfield, now called Batts Boulevard and Main Street. A portion of the old route north of downtown was removed due to the construction of a quarry. US 41 was rerouted onto Memorial Boulevard, a 4 lane highway, around 1961 after its completion.
US 431 followed a more eastern route prior to at least 2010 south of Springfield. This route had a different bridge crossing at Carr Creek that has since been demolished. North of the bridge, it followed what is now called Main Street. It intersected US 41 at the junction of what is now Main Street, A C Street, and 11th Avenue. It ran with US 41 after this intersection, until its own rerouting on Memorial Boulevard in 1961. US 431 was rerouted onto Tom Austin Highway around 1983.[10]

Springfield, Tennessee, operates under a council–manager form of government, a system it adopted in 1990. In this structure, the City Manager is appointed by and reports to the elected legislative body and is responsible for overseeing the daily operations of the city’s departments and services.[21]
The city’s legislative authority is vested in a seven‑member Board of Mayor and Aldermen (often abbreviated BOMA), which serves as the principal policy‑making body. The board consists of a Mayor elected at‑large and six aldermen, each representing one of the city’s six wards, all serving four‑year terms. The Board enacts ordinances, resolutions, and major plans, and holds regular meetings, typically on the third Tuesday of each month.[22]
Under the charter, the Mayor presides over Board meetings and serves as the ceremonial head of the city but does not have veto power. Eligibility for elected office requires that the Mayor and aldermen be qualified voters who have resided in the city or their ward for at least one year prior to the election.[22]
The City of Springfield is a full‑service municipality, providing utilities such as electric, natural gas, water, wastewater, and sanitation services directly to residents, and also oversees other departments, including Public Works and Human Resources.[22]
