(2 up, 2 down) thereafter. Traffic Mainly concentrated in Madian - Huilongguan section. Shangqing Bridge is a traffic bottleneck. Potentially slow after Juyongguan (mountainous). Long traffic jams can clog up to the extent that the stretch from Madian to Jianxiang can become a three-lane car park during rush hour. For the stretch after that until the Qinghe Toll Gate, the right part of the expressway can get clogged up with vehicles leaving the expressway. During both rush hour periods, the Huilongguan exit is likely to form a huge traffic line.

Needless to say, a stretch of Great Wall is also next to the Pass. Shuiguan Exit - Exit No. 16: The Great Wall at Shuiguan is little-known and extremely steep. From the top there are views and a place to see (though not visit up-close) a stretch of the Wall which has yet to be repaired (also known as "the wild Great Wall"). Note: There is no entry back into the expressway; you must proceed by minor routes back to Juyongguan. Badaling Exit - Exit No. 18: The most famous and most frequented of all three exits is the one at Badaling.
