State Route 198 (SR 198) is an east–west state highway in the U.S. state of California that runs from U.S. Route 101 (US 101) south of King City to Sequoia National Park. It connects the California Central Coast to the mid–Central Valley through Hanford and Visalia, although the most developed portion is in the Central Valley itself. SR 198 intersects the major north–south routes in the Central Valley, including Interstate 5 (I-5), SR 33, and SR 99.
The highway that would become SR 198 was approved for construction in the 1910s through three bond issues, and was added to the state highway system in 1934. Parts of the highway were upgraded to freeway during the 1960s. Another portion was converted to an expressway in between Hanford and Visalia, and was completed in late 2012.
