No current routing. Field reports indicate that the old routing is still signed. The old routing was relinquished in June 2001.
In 1965, Chapter 2068 defined Route 274 as “Route 5 near Balboa Avenue to Route 103.”
In 1969, Chapter 294 changed "Route 103" to "Route 15".
During 1971, Route 274 was completed to state highway standards between
I-5 and I-805. By 1975, Route 274 was a complete highway between I-5
and Route 163, with an adopting routing east to I-15 (as shown on the map
to the right). Route 274 was completed to I-15 by 1990.

The routing was deleted in 1999 by AB 1650, Ch 724, 10/10/99. It still shows up in the CalTrans photologs in 2001, and a few signs remain. It was once signed as BR US 101.
As signs get replaced on I-5, references to Route 274 are disappearing; however, Route 274 is still well marked upon Balboa.
Originally (i.e., circa 193), Balboa Avenue was a major locally
maintained road from Grand Avenue in the San Diego neighborhood of Pacific
Beach east to Morena Boulevard. Balboa Avenue as originally
configured intersected US 101 (LRN 2) at what is now Mission Bay Drive
(then Grand Avenue). By 1958, it had been extended E into the Clairemont
neighborhood. Balboa Avenue was not part of the state highway system
before 1965.
