This property is a good distance from JBLM. The area of this home is far from the highway, no direct routes, and has many lights before you reach I-5. After that you have to deal with the traffic on I-5 not only going through Fife but the Tacoma dome/downtown area plus JBLM traffic. All of these traffic areas bunch up during rush hour. When I was at Ft. Lewis I traveled to North Tacoma and it would take me anywhere from 20-45 depending on the severity of the traffic. However, Google maps currently has it at 30 minutes. Browns point is on the other side of the port still and you will have no choice but to deal with downtown traffic. If you want to cut your commute time I would suggest areas around JBLM such as Lakewood, Spanaway, Parkland, Puyallup, DuPont, Tacoma, etc.
hope this helps!
