On that route, in addition to the almost-always very heavy traffic (shown by the red areas on the Google Maps route) there's also frequent construction zones, which are often lane reductions to boot.
Too, this moment on Friday is right in the middle of "rush hour" (a phrase ...
Heavy traffic in busy cities is normal. It would be similar if you were trying to get in and out of NYC or Boston or San Francisco at this hour. Is this news?
