I took a little "day trip" on Saturday, from my home in San Diego County, up north to Burbank, CA. My purpose was a professional workshop. My routes were I-15 North, CA-78 West, I-5 North, CA-134 West, and a mile on CA-170 North.
There were two spots where CalTrans had closed down one lane of I-5, one was right around Norwalk. That wasn't bothersome at 8:00 on a Saturday morning, but southbound at 2:30 pm, it was a nightmare.
Even where there was no construction, traffic was a nightmare yesterday. It took me 2 hrs 10 min to make it northbound to my workshop. It took me 3 hrs 15 minutes to make it home (not including my stop in San Juan Capistrano for bathroom and something to eat).
Next time, I go back to my other route, which avoids I-5.
