Once you have reached the University of Maryland, you will want to get on Campus Drive. If you are coming down Route 1 from the North, Campus Drive will be about 2 1/2 miles from the Beltway, on your right. If you are coming up Route 1, Campus Drive will be on your left, after you have passed Fraternity Row on your right and the Rossborough Inn to the left. Once you are on Campus Drive, take the first right and then the first left (except for two parking lot entrances), onto Stadium Drive. Lot T will be on your left, lot G behind the buildings to the right, and Parking Garage II will be ahead at the intersection of Stadium Drive and Regents Drive.
The Math building is the only domed building on campus, across from the big "M" on Campus Drive. You should see it as you enter campus on Campus Drive.
