From the beltway (I-495), take the exit for I-66 East towards Washington. (This is a left-hand exit if you are on the outer loop.) Take Exit 69 from I-66 to US 29 Lee Hwy.
At the end of the ramp, turn right at the light. This is US 29 Lee Hwy.
After the third light, you will see the Sunrise Senior Living Community on the left followed by a parking lot. Please park in the lot--Demosphere House is adjacent to the lot and directly on the main road, North Washington Street.
Enter through the downstairs entrance and say hi!
