Big Tujunga Canyon Road

[Max Rockatansky]

Big Tujunga Canyon Road is approximately 13-mile-long rural highway located mostly in the San Gabriel Mountains of Los Angeles County.  As presently configured Big Tujunga Canyon Road begins at Angeles Forest Highway (County Route N3) and extends west to Oro Vista Avenue in the Los Angeles neighborhood of Sunland. 

The earliest parts of Big Tujunga Canyon Road were constructed between Mount Gleason Road northeast to Hoyt Ranch at Vasquez Creek in the 1890s.  The highway was extended east to Big Tujunga Dam in 1931.  In 1958 Big Tujunga Canyon Road would be extended east again from dam to a terminus at Angeles Forest Highway. 

In 1959 the corridor of Big Tujunga Canyon was added to the definition of planned Legislative Route Number 266.  Said planned state highway was developed as a trans-San Gabriel Mountain corridor which would have connected with US Route 466.  During 1964 the Big Tujunga Canyon corridor would be transferred to Segment B definition of California State Route 118.  Ultimately the California Highway Commission never made a formal route adoption for a State Highway in Big Tujunga Canyon.  The corridor of Big Tujunga Canyon Road was planned to be extended west to Foothill Boulevard but ultimately only was ever built to Oro Vista Avenue in the 1970s.
