This street runs along the east side of campus (you can catch it at Dong Mer). Besides leading to JiShuiTar subway station in the opposite direction, when you turn left from XueYuanNanLu or Dong Mer, you'll hit this intersection with the third ring road (SanHuan BeiLu). On the other side of the bridge and on the right is "WuMart," a large supermarket with overpriced imported fruit and lots of neccessities. It seems like a good place to go to until you realize there's a supermarket much closer to Lanhui through the gates. Then again, people love the name "Wumart." Incidentally, for pedestrians on the far side there's a subway, which is typical at large Beijing intersections.
