Post 1964 Signage History
In 1963, Route 171 was defined as "Route 5 near San Diego to Route 805 via Switzer Canyon."
In 1994, the previous routing for Route 171, from Route 5 near San Diego
to Route 805 via Switzer Canyon, was deleted per AB 3132, Chapter 1220.
This was part of a road system first proposed in 1926. It would have
started at I-5 near downtown San Diego, run northeast to connect with
I-805 near the I-8 junction, crossing several canyons, residential areas,
and the Balboa Park Municipal Golf Course. A remnant of what was to be a
freeway-to-freeway connection exists at the I-5 and Pershing Drive/B
Street interchange (Exit 15B).
According to Tom Fearer, Switzer Canyon was the subject of numerous
proposals by the San Diego City Council to be added to the City Park
System beginning in the late 1970s. This culminated in 1987 when the
City of San Diego purchased Switzer Canyon which effectively blocked the
planned route of Route 171.

In 1933, Chapter 767 defined the route from "[LRN 60] near Huntington

added to the highway code as LRN 171, with the routing:
