If you have ever shopped at any of the stores in the shopping center at Four Points where HEB is, you know it can be a pain getting out of the parking lot.  The exit that takes you to 2222 right before it intersects with 620 can be a nightmare.  This is especially true when traffic is high and in bad weather.  So why even try to get out of the parking lot this way?  It always amazes me that people will sit and wait and wait and wait some more to exit the parking lot there when traffic is heavy on 2222.  I am not patient enough to sit there and wait until someone is niche enough to let me on 2222.  I also am not the kind of person to blast aggressively into traffic risking being slammed by an SUV. 

If you have anything even close to a practical mind, do what I do.  Exit the parking lot to the north.  You can simply turn left on to Four Points Drive, get to the traffic lignt and turn safely on to 620.  Whether you are staying on 620 heading to Steiner Ranch, past Mansfield Dam to Lakeway or out Volente Road, you have a much safer route.
