Mission Avenue within the city of Oceanside between Coast Highway (Historic U.S. 101 and San Diego County Route S-21) and presumably either Foussat Road or Frazee Road is designated as California 76 Business. Few if any route markers for the business route are present along Mission Avenue itself, but two markers are prominently posted, one each on Interstate 5 north and south.

The business route was created in November 1995 when the initial segment of California 76 expressway opened to traffic, extending from Interstate 5 and CR S-21 (Coast Highway / Historic U.S. 101) east to Foussat Road. The second phase of the expressway project (completed 1999) installed overpasses wherever Mission Avenue met the expressway. This project might have resulted in an extension of the business route further east to Frazee Road, but it is not clear that any signage was added to reflect this presumption. The intersection between Mission Avenue and Frazee Road was reconstructed so that Mission Avenue no longer directly merged back onto the new expressway, so the business route is essentially disconnected from its parent route even if it made it as far east as Frazee Road.3

Finally, looking at the area in 2012, no "Route 76 Business Next Left" signage is evident along westbound California 76 at either the Frazee Road or Foussat Road intersections. Given the lack of reassurance and trailblazer signage, and also the undetermined eastern end, it is arguable as to whether California 76 Business still exists at all.
