From SR520 eastbound:
1. Just after the I-405 overpass, move into the far right lane (it's both an HOV and freeway entrance/exit, so be alert for merging traffic).
2. Take the 124th Avenue NE exit.
3. The exit will split into 4 lanes – keep in the left-most lane.
4. At the end of the exit, turn left on to Northup Way.
5. Go approximately 1/10th of a mile and turn into the first driveway on the left. IronWorks' is located on the ground level of a two-story office complex. You'll see IronWorks' yellow and black sign just above the door.
6. If you miss the first entrance, there is a second entrance located approximately 50 feet further down Northup Way.
