Traffic Advice
If you are heading through the area, the backup has been stretching north toward the I-5/I-805 merge. You might want to consider:
I-805 South as a primary bypass.
Pacific Highway or Morena Boulevard for local access if you are already near the Mission Bay/Clairemont area.
Crews have been working on uprighting the vehicle and clearing any potential spills, but lane closures often persist for several hours during these types of recoveries.
