State Route 94 marker

State Route 94 (SR 94) is a highway in the U.S. state of California that is 63.324 miles (101.910 km) long. The western portion, known as the Martin Luther King Jr. Freeway, begins at Interstate 5 (I-5) in downtown San Diego and continues to the end of the freeway portion past SR 125 in Spring Valley. The non-freeway segment of SR 94 that continues east through the mountains to I-8 near Boulevard is known as Campo Road.

The Campo road served as a wagon road providing access to eastern San Diego County as well as Imperial County. The road was added to the state highway system in 1933, and signs for Route 94 were posted along local roads later that decade. Efforts to convert the western half of the route to a freeway got underway in the 1950s, and the freeway was complete by 1962 west of the road that became SR 125. Construction continued east to Avocado Road over the next few years. Various proposals for widening the highway have come from the California Department of Transportation (Caltrans), but local opposition resulted in the delay or cancellation of many of these proposals.

SR 94 is an east–west freeway that begins at the eastern end of the one-way couplet of F and G streets in southeast San Diego. The freeway continues through an interchange with I-5 just east of downtown. Following this, the route goes through the neighborhoods of Sherman Heights, Grant Hill, , and Mount Hope, where there is an interchange with SR 15. Shortly thereafter, SR 94 intersects I-805 in Chollas View before continuing east through Emerald Hills and Chollas Creek into the city of Lemon Grove. Passing by the Marketplace at the Grove Mall, the freeway forms the boundary between Lemon Grove to the south and La Mesa to the north, up to the SR 125 interchange where SR 94 turns east. At this point, SR 94 leaves both cities and enters unincorporated Spring Valley and Casa de Oro.
