[edit] Route description

SR 15 continues seamlessly past the southern terminus of I-15 at I-8 in San Diego. The route interchanges with State Route 94 and Interstate 805 and terminates at Interstate 5 south of Downtown San Diego. On the northbound conversion to I-15 at I-8 there is no "End SR 15" sign.

[edit] History

From 1934 to the 1964 renumbering, State Route 15 was assigned to a route from San Pedro to Pasadena. This was renumbered State Route 7 in 1964 (to avoid conflicts with I-15) and Interstate 710 in 1984, 3 years after State Route 11 which replaced the green shields with Interstate 110 in 1981.

Present SR 15 was signed after the creation of I-15 in 1968. Since I-15's terminus was at I-8, SR 15 was signed mostly along 40th Street and Wabash Boulevard in San Diego to its merge with I-5. The freeway conversion lagged for years and was not completed until January 2001. For this reason the freeway is often referred to as the 40th Street Freeway.

[edit] Future Aspirations

Redesignation of SR 15 as I-15 will eventually occur when the freeway's interchange with SR 94 is updated to Interstate standards. The interchange currently has left-exits and blind merges, and is due to be updated with a long-awaited widening of SR 94 in 2008. At that time SR 15 will be resigned as part of I-15. The remaining portion of SR 15 conforms with Interstate standards.

[edit] State law

Legal definition of Route 15: California Streets and Highways Code, Chapter 2, Article 3, Section 315
