What kind of traffic/travel time I should expect driving to and from Woodbridge and Fort Belvoir?

Alexander,

I live outside Belvoir. Woodbridge is close, but there is a traffic choke point to cross the Occoquan. You can alleviate some of that by sneaking up route one sometimes. If you're in Woodbridge itself and going to work at 6-7ish expect a min of25-35 minutes. There are some affordable neighborhoods on the north side of the Occoquan you might consider checking too. (Newington, Kingstowne, Hayfield)

Good luck!

I will echo what the good LTC Eugene Chu said and suggest giving yourself a little extra time to commute. If you are going to live in Woodbridge and commute to Belvior, VRE is a good option too. I take the VRE from Fredericksburg to DC for work every day and it's clean and the conductors are nice. You would simply take the VRE from Woodbridge to Franconia-Springfield and then get off and take a bus to post. There's a bus that runs from Franconia-Springfield to the base. It's a lot less hassle and frustration than dealing with traffic on 95. Good luck and welcome to the area!

I work in DC. Traffic can fluctuate depending on departure time and on what lane you use (30-45 minutes). If you leave earlier for PT, use pay express lane or offer to pick up "slugs" (organized hitchhikers), you may have shorter commute (20-30 minutes).
