All four were taken to a hospital but injuries to George were most serious. The injuries to Yee, her husband and the officer were described as non-life-threatening.

The crash shut down the tunnel for about 90 minutes Friday afternoon. Drivers who were already in the tube had to back out single-file while emergency crews worked their way in to the crash scene.
