The three highways head to the west-southwest concurrently and enter Dodge County.

Shortly afterward, SR 165 departs to the northeast along the Chauncey-Rhine Highway and eventually enters Chauncey.

The four have a brief wrong-way concurrency in the town, until the blinker-light intersection with Milan-Chauncey Road and Chauncey-Dublin Highway, the latter of which is where SR 165 departs to the northeast.

It continues to the northeast and very briefly enters Laurens County.

Then, it re-enters Dodge County and meets its northern terminus, an intersection with SR 46 northeast of Eastman.
