San Diego
County Sign Route S17

[Click here for a key to the symbols used. Some county routes were constructed with federal funds. These routes are indicated as FAP (Federal Aid Primary), FAU (Federal Aid Urban), or FAS (Federal Aid Secondary). If no funding source is shown, no federal funds were used. Note that while some segments seem to have the same attributes, they may differ in the county-local road number assigned to the segment, or in the Caltrans Map Sheet number.]

Routing

1. E Street in Chula Vista from I-5 to Bonita Road (FAU, 2.09 mi)

2. Bonita Road in Chula Vista from E Street to the Chula Vista city limits (FAU, 0.25 mi)

3. Bonita Road from the Chula Vista city limits to Glen Abbey Blvd (FAU, 0.32 mi)

4. Bonita Road from Glen Abbey Blvd to Glen Abbey Blvd (FAU, 0.56 mi)

5. Bonita Road from Glen Abbey Blvd to the Chula Vista city limits (FAU, 0.69 mi)

6. Bonita Road in Chula Vista from the Chula Vista city limits to Otay Lakes Road (FAU, 0.62 mi)

7. Bonita Road from Otay Lakes Road to San Miguel Road (FAU, 1.35 mi)

8. Bonita Road from San Miguel Road to Sweetwater Road (FAU, 0.26 mi)

9. Sweetwater Road from Bonita Road to the South Bay Freeway (Route 54) (FAU, 1.06 mi)

   Note that the meeting of this segment and the next does not occur at an intersection, but underneath a freeway bridge, as the intersection of Route 54 and Worthington was eliminated in 2004 when the South Bay Parkway was upgraded to the South Bay Freeway. The significant grading work that was part of this upgrade as well as the construction of the ramps between the new South Bay Expressway (Route 125 TOLL) and the South Bay Freeway probably made an interchange impractical. In fact, the significant grading work for the Route 54/Route 125 interchange resulted in County Sign Route S17 actually having a physical discontinuity where this segment and the next would have met. This appears in Google Earth satellite imagery starting April 30, 2004 and finally on December 25, 2006.
