You are correct and it would be open towards 50. Route 7 is to the back of Home Depot. The top of the deck is the same level as rte 7. There are shops/stores on two different levels there so the deck is kind of like an overhang providing extra parking. The Home Depot is on the lower level with a ramp leading from it to the top of the deck. Parking is available on top of or under the deck.

It's a very very congested area. 3 major routes come together there. The traffic is some of the worst in Northern Virginia that I have experienced. Immediate guesses are that the shooter could have been on the access road bordering route 50 if he/they shot from their van. My guess is he shot from across 50 and then ran to a waiting vehicle possibly blocks away???. who knows. A lot of these witness reports are unconfirmed and contradicting.

Regarding a vigilant armed citizen shooting the shooter after he disclosed his position. He's been very careful NOT to disclose his position. Thus ONE shot only.
note, my humble opinion, and worth .02 cents.

IIRC (it's been more'n 10 years since I have been at that plaza - and it was much smaller with no deck then), 50 runs beneath the Seven Corners intersection itself, while 7 is up top. 50 has no lights there, just offramps, but 7 has lights - is this correct?

If so, and if the car left headed east on 50, my impression of this guy having intimate knowledge of the DC area highway system would inch closer toward a realistic issue.
