The Lankao–Xuchang Expressway (Chinese: 兰考－许昌高速公路), often abbreviated as Lanxu Expressway (Chinese: 兰许高速) and designated as S37 in Henan's expressway system, is a 114-kilometre (71 mi) long regional expressway in Henan, China. Currently it's fully completed.
History
[edit]Before July 8, 2024, this expressway was a part of Lannan Expressway (Chinese: 兰南高速公路) which started at Lankao and ended at Nanyang. The first phase of the expressway is from Xuchang to Nanyang via Pingdingshan and was called as Xupingnan Expressway (Chinese: 许平南高速公路). This section was opened on 12 December 2004 and provided expressway connections to the above-mentioned three major cities in Henan.[1] The second phase (Lankao–Xuchang section, called Lanxu Expressway) was opened on 19 November 2005.[2] The third phase was opened on December 19, 2005.[3][4]
The Xuchang–Ye County section has also been designated as G0421.
On July 8, 2024, the latest version of Henan Expressway numbering was released by Henan Provincial Department of Transportation.[5] The previous Henan S83 (Lankao–Nanyang Expressway) was abolished. Instead, the Ye County-Nanyang section was redesignated as G3612, and the name Lanxu Expressway was restored on Lankao-Xuchang section.
