Southern Terminus

The entire path of OH 721 is always either straddling, or located within one mile of, the Darke - Miami County Line. This is the JCT OH 49 shield on southbound OH 721 as it approaches its southern terminus in extreme southwestern Miami County, northwest of Phillipsburg.

Here is the perspective of northbound OH 49 as it nears the OH 721 intersection. Note the county line sign that stands between where Eric took this photo and the intersection itself. Eric is standing in Montgomery County, while the junction of OH 49 and OH 721 is just into Miami County.

Northern Terminus

The northern endpoint of OH 721 is at a T-intersection with OH 185, north of Bradford, on the Darke - Miami County Line. The first photo provides an overview of OH 721's northern terminus; the second one shows a close-up of the END OH 721 and OH 185 shields present at the back of the intersection.

The shield shown here, which faces eastbound OH 185, points to the start of OH 721. A county line sign marking the entrance into Miami County and departure from Darke County immediately follows the intersection.
