History

When defined in 1963, the route began at I-280 and ended at US 101. In 1984, a segment of SR 84 in the vicinity was swapped with SR 114, moving SR 114 from I-280 to SR 84, which followed Willow Road, as it does today. In 1990, however, the I-280 section was truncated and the terminus was switched to US 101.
