As I wrote in an earlier post, Tysons can be a good if not great place for biking and hiking. But when Fairfax County shuts down one northbound lane of Tysons Boulevard to vehicular traffic beginning on July 6, you must at least try one time for yourself. Capital Bike Share station map
The Bike Share bikes are heavy, so if you procure one, you will go slow, not such a bad thing even in these pandemic times. Tysons Boulevard is not as busy as International Drive but believe me it can get a bit of traffic. So, closing it off to allow pedestrians and cyclists is a good tradition to have.
Let me remind you that in addition to access to Tysons Galleria, you can easily access one of the few trails in Tysons. Even before you enter the closed portion of the street, take a right down West Branch and then enter the trail on your left. It will take you to the (artificial turf) soccer field.
