SR 289 is a 10.52-mile (16.93 km) highway that serves Peña Blanca Lake, passing through sparsely inhabited territory.

[2] From its eastern terminus at the frontage road nearly 400 feet (120 m) east of the I-19 interchange, the highway heads in a western direction before curving towards the southwest.

The highway eventually curves back towards the west until it turns north towards the lake.

[4] The route was established as SR 289 in 1959, when it only ran west from US 89 to the Coronado National Forest boundary.

[5] The next year, the route was extended westward to Peña Blanca Dam.
