Route description
SR 312 begins at an intersection with SR 60 in Birchwood, a small community in northeastern Hamilton County, and travels southwest for approximately 13 mi as Birchwood Pike through rural farmland, before turning east and intersecting with SR 58 near Harrison. The route then runs north concurrently with SR 58 for about 1/2 mi, before turning east as Mahan Gap Road. The route runs through the community of Snow Hill, and about 2 mi later comes to a four-way intersection with Ooltewah-Georgetown Road, a major connector road between the communities of Ooltewah and Georgetown. The route then crosses Mahan Gap in White Oak Mountain, and about 1+1/2 mi later crosses into Bradley County, where it becomes known as Harrison Pike. About 2+1/4 mi later it intersects with Bancroft Road, a connector to McDonald. The route continues for another 2+1/2 mi through a rural residential area, before turning sharp east, and entering the community of Prospect. About 1+1/2 mi later the route crosses I-75, but does not interchange. The route then continues for another 2 mi, crossing Candies Creek, Candies Creek Ridge in a gap, and entering Cleveland, before coming to an intersection with US 11 Bypass (Keith Street). The route continues east as Inman Street for another 1/5 mi before meeting its eastern terminus with US 11/US 64 (Ocoee Street, Broad Street) in downtown Cleveland. Also at this intersection US 64 splits off from US 11, and continues east as Inman Street.
