My Dad works at JCPenney in Carlsbad. The drive from his house in Bonsall is approximately 12 miles. Normal drive time to work with no traffic is approximately 20 minutes. My Dad's current drive time to work is 50 minutes. The drive back from work is the same story.
Although there are many factors that can cause this Los Angeles-type traffic, one sticks out above the rest: the two-lane highway, aka the San Luis Rey Mission Expressway, aka the CA-76. This two-lane highway begins at the I-15 and, going west, ends at the Melrose Drive intersection. After this it becomes a four-lane highway until the I-5.
This throughway may have flowed well in the past, but times have changed. The drivers from Bonsall would benefit greatly from an expansion. In comparison, the CA-78 has more than four lanes from I-5 to the city of Ramona. Of course, the CA-78 could benefit from some more lanes, but Bonsall has yet to have the pleasure of a four-lane highway. Bonsall is growing. The CA-76 needs to catch up.
Watch the traffic on the morning commute.
