If there is a major event going on at the Fairgrounds, including the Fair, unless you are actually going yourself, I would suggest avoiding heading northbound on I 5 if at all possible. It has been known to be backed up as far as Hazel Dell.

As with any road closiers in any area its annoylng but nessesary
