There is a small connector in this intersection to allow southbound M-33 traffic to turn west along M-68 instead of merging into the combined eastbound M-33/M-68 traffic. The two highways continue together in a concurrency through the wooded, hilly terrain to the unincorporated community of Tower, where they cross the  Black River. It is east of this river crossing where the highway meets the southern end of F-05, a County-Designated Highway that runs along Black River Road.
