Ohio State Route 334 is a short east-west highway on the north side of Springfield, Ohio. It stems easterly from US Route 68 to provide part of a northern bypass around Springfield. The western end of Ohio Route 334 is a fully-directional interchange with US Route 68; both highways at this junction are divided four-lane freeways. Ohio Route 334 continues east as a freeway, past an interchange with Ohio Route 72. The freeway shenanigans stop quickly, and Ohio Route 334 acts as a surface road for the rest of its eastward progression to Ohio Route 4. Ohio Route 4 allows traffic from Ohio Route 334 to continue northeasterly.
