Wudaokou (Chinese: 五道口; pinyin: Wǔdàokǒu), whose name is a literal reference to the fifth level crossing of the Jingbao Railway, is a neighborhood in the Haidian District of North West Beijing. It is around 10 km (6.2 mi) from the center of Beijing, between the fourth and fifth ring roads, and has good public transport links including a train station on Line 13 (the CityRail line) of the Beijing Subway. It became a commercial center in Haidian during the 1950s following the establishment of schools. Until as recently as 2001 the area consisted mainly of Hutong neighborhoods and late 1960s apartment blocks, but major development has erased many of these old structures, replacing them with luxury apartments and science parks.
