Khlong Chong Nonsi runs from [[Surawong Road|Surawong]] road all the way to the [[Chao Phraya river]], covering a distance of approximately {{convert|4.5|km|mi|1|abbr=on}} through the districts of [[Bang Rak]], [[Sathon]], and [[Yan Nawa]]. The canal also gives its name to [[Chong Nonsi]], one of the two subdistricts (''[[khwaeng]]s'') in Yan Nawa district, where it empties into the Chao Phraya river. At present, the canal runs parallel to the entire length of [[Naradhiwas Rajanagarindra Road|Naradhiwas Rajanagarindra]] road. Along its course, it intersects with several roads, including [[Chan Road|Chan]] road and [[Rama III Road|Rama III]] road. The [[BTS Skytrain]] [[Silom Line]] is located at its northern end, while the [[Bangkok BRT|BRT]] bus system operates along much of the canal. The width of the canal at its mouth is about {{convert|20|m|ft|1|abbr=on}}, while the section running along Naradhiwas Rajanagarindra road is approximately 6–8 m (19.7–26.2 ft) wide. {{convert|6|m|ft|1|abbr=on}}–{{convert|8|m|ft|1|abbr=on}} wide.<ref>{{cite web|url=https://www.facebook.com/prbangkok/posts/3048753071890960/|title=🌟"คลองช่องนนทรี" คลองกลางกรุงที่ถูกลืม🌟|trans-title=🌟”Khlong Chong Nonsi” the forgotten downtown canal🌟|language=thai|date=2020-11-20|accessdate=2022-07-29|work=Facebook|author=BMA by PR Department}}</ref>
