The route's southern terminus is at a T-intersection with SR 41 about 1.50 miles (2.41 km) north of Aberdeen.

The entirety of SR 763 is located in the southeastern quadrant of Brown County.

SR 763 is not a part of the National Highway System, a network of highways deemed most important for the economy, mobility and defense of the nation.

Its original routing is the same as that which it utilizes today through southeastern Brown County.

No changes of major significance have taken place to the state highway since its designation.
