The longest canal in Thailand with distance is 72 km (about 44 mi) from the downtown Bangkok to the east in Chachoengsao province.
Khlong Saen Saep was dug during the reign of King Nangklao (Rama III) in the early Rattanakosin period.
Khlong Tan originated as a three-way junction where the end of Phetchaburi met Ramkhamhaeng, and Pridi Banomyong roads.
The area is served by the Ramkhamhaeng station (A5) of the State Railway of Thailand (SRT), whose Airport Rail Link (ARL) passes through.
Khlong Saen Saep boat service ran through the area, docking to pick up passengers at Sapan Klongtun pier (E13) near the intersection.
