Route 121 is a short highway in Clinton County, Missouri. It begins at U.S. Route 69 (US 69) south of Cameron and ends at Wallace State Park where the road becomes Route HH. It served as a connector between US 69 and the state park since 1935.

Route description

Route 121 begins at an intersection with US 69 just south of the U.S. Highway's interchange with Interstate 35 (I-35) in eastern Clinton County. The route is entirely rural; both sides of the highway are dotted with acreages surrounded by farmland. As the road approaches Wallace State Park, it becomes a tree-lined highway. The route ends at a Y intersection with Route HH, which continues east, and the southerly access road to the park.

History

Route 121 was designated in 1935 and first appeared on the 1936 state map. Since it has been in the state highway system, it has always connected Wallace State Park to US 69.

Major intersections

The entire route is in Shoal Township, Clinton County.

South Carolina Highway 121

South Carolina Highway 121 (SC 121) is a major state highway that runs north and south in the western part of the U.S. state of South Carolina. The road is actually part of a long multi-state route that also goes through Florida and Georgia. Some see it as a de facto auxiliary route from U.S. Route 21 in Rock Hill. Efforts to have the road upgraded to such status have failed however.

Route description

South Carolina Highway 121 continues its concurrency with U.S. Route 25 from Augusta, Georgia into North Augusta, South Carolina. In the Schultz Hill section of North Augusta, US 25/SC 121 leaves the concurrency with US 1 and US 78, and heads north. Still within North Augusta, it has an interchange with Interstate 520 at Exit 22 and Interstate 20 in South Carolina(at Exit 5).

In Trenton, US 25 turns left onto SC 19 and SC 121 becomes an independent route for the first time. From there it runs mainly through rural western South Carolina. Johnston is where the route serves as the northern terminus of SC 191, and later crosses SC 23.
