State Route 289

Arizona State Route 289 is a 10.5 mile highway connecting Interstate 19 with Pena Blanca Lake in Santa Cruz County. The state highway stems west from I-19 (Exit 12) and follows Ruby Road southwest toward Pena Blanca Lake, located within the Buenos Aires National Wildlife Refuge. Pena Blanca Lake was constructed in 1958 by the Arizona Fish & Game Department, with SR 289 being added to the state highway system two years later.

SR 289 travels along Ruby Road for most of its course to Pena Blanca Lake. Otherwise, this confirming marker for the state highway stands beyond the interchange with I-19.

Pena Blanca Lake was constructed by the Arizona Department of Fish and Game in 1958. The lake is a hidden treasure, stocked with fish, but has had many issues over the years, including former mine tailings laced with mercury washing into the lake in the early 1990s.
