The main feature is Caihuying Bridge (simplified Chinese: 菜户营桥; traditional Chinese: 菜戶營橋; pinyin: Càihùyíng Qiáo). It links the 2nd Ring Road, which does a turn from south to east, with a connection road to the Jingkai Expressway and another route to the western 3rd Ring Road.
It is one of the few super-overpasses in Beijing to connect more than two roads.
