Upon crossing Eckert Road, SR 546 enters Troy Township. The highway next bends to the northeast, and amidst the continued blend of woods and farmland with the occasional house, crosses the Kings Corners Road intersection. As the highway turns to the north and then northeast, a series of dead-end side streets begin to appear, while still amid rural terrain. When SR 546 arcs back to the north, it then crosses into the village of Lexington. Now known as Frederick Street, the state highway passes into a primarily residential area. It intersects Clever Lane, which connects the highway to Lexington High School just two blocks to the west. Continuing north, SR 546 goes by Central Elementary School and Lexington Middle School. After crossing a side street, Church Street, the state highway passes by a couple of businesses prior to coming to an end at a signalized intersection where it meets US 42 and SR 97. Proceeding north from this intersection is Plymouth Street, which becomes county-maintained Lexington-Springmill Road once the roadway departs the village limits.
