History

In 1933, a road from Brea to Chino was added to the state highway system. It was designated as Route 177 in 1935. In the 1964 state highway renumbering, this became part of SR 142. A routing from Chino to Upland was added to the state highway system as Route 274 in 1959, and was added to SR 142 in the 1964 renumbering from SR 71 to SR 30 (later SR 210), but no highway has been built along that route.
