SR 128 begins at an intersection with U.S. Route 50 (US 50), in Cleves, on the west bank of the Great Miami River. The highway heads north as a two-lane highway passing through woodland and parallel to the river. The road curves northeast, before curving southeast, passing through commercial properties. The route curves northeast and has an interchange with Interstate 74 (I–74) and I–275. North of the interchange SR 128 curves due north passing through Miamitown. The highway curves northwest before leaving the town. The route heads northwest passing through a mix of farmland and woodland. The roadway enters Ross and begins a concurrency with SR 126. The concurrency passes through residential properties, with some commercial properties.[4][5][6]

On the northeast side of Ross the road has an interchange with US 27, this interchange is the eastern end of SR 126 concurrency. The routes leaves Ross passing through woodland and farmland. The highway curves due north heading towards Hamilton. As the road enters Hamilton it passes through residential properties, before turning due east, crossing over the Great Miami River on the Columbia Bridge. After crossing the river the highway heads into another residential neighborhood along Pershing Avenue. The highway ends at US 127.[4][5][7]

SR 128 is not part of the National Highway System, a system of routes important to the nation's economy, mobility and defense.[8][9]

SR 128 was first signed in 1923 and the entire route was paved in 1928.[2][3][10][11] In 1935 US 50 Bypass was signed concurrent with SR 128 from US 50 north to US 27.[12][13] The US 50 Bypass was decommissioned in 1974.[14][15] SR 128 formerly extended 0.38 miles (0.61 km) north along US 127 in Hamilton then east along High Street for 0.59 miles (0.95 km) to end at SR 4, SR 129, and SR 177.[16] By 2007, the terminus had been truncated to the intersection of US 127 and SR 129/SR 177 and by 2013, its current northern terminus.[17][18]
