The Dazhushan Tunnel (大柱山隧道) is a 14.484 km (9.0 mi) railway tunnel in Baoshan, Yunnan, China as part of the Dali–Ruili railway. Construction of the tunnel began in August 2008 and was carried out by the First Engineering Bure Crec (中铁一局). Its construction was expected to take five years, but because of extreme geological conditions along its alignment, completion took place on 28 April 2020, after 12 years of construction. As another tunnel, Gaoligongshan Tunnel, along the railway line was still under construction, it did not enter service until 2022.
