Ratchawithi Road

It begins in Ratchathewi district at Sam Liam Din Daeng Junction, where it intersects with Din Daeng Road and Ratchaprarop Road, and runs northwest, past Victory Monument Circle, through Dusit district, and ultimately crossing the Chao Phraya River on Krung Thon Bridge and ending in Bang Phlat district at Bang Phlat Intersection, where it intersects with Sirindhorn Road and Charan Sanitwong Road.

The name "Sang Hi" comes from Chinese (囍), and means "exceedingly happy".

[1] The original road stretched only from behind Dusit Palace to the edge of the Chao Phraya.

The term is derived from the Pali/Sanskrit, rāja + vīthi, and means "royal way" or "king's road".

At Ratchawithi Intersection, where it meets Rama V Road near Chitralada Royal Villa and Dusit Zoo at about 6:30 am on Sunday October 14, 1973, there was a clash between a group of protesters demanding a constitution and police.
