Sam Liam Din Daeng
Sam Liam Din Daeng (Thai: สามเหลี่ยมดินแดง, pronounced [sǎːm lîam din dɛ̄ːŋ]) is a road junction located in the Thanon Phaya Thai Subdistrict of Ratchathewi District, in central Bangkok. It is a three-way intersection where Ratchawithi Road, Ratchaprarop Road, and Din Daeng Road meet. The name of the junction, Sam Liam, means "triangle" in Thai, referring to its triangular shape. The junction is also notable for its overpass, which connects Ratchawithi Road to the Victory Monument area nearby.
This junction is often confused with the similarly named Tai Duan Din Daeng Junction (Thai: แยกใต้ด่วนดินแดง, pronounced [jɛ̂ːk tâːj dùan din dɛ̄ːŋ]), located further along Din Daeng Road in Din Daeng District, where it intersects with Vibhavadi Rangsit Road. That junction features both an overpass and an underpass.
Sam Liam Din Daeng has long been recognized as one of the locations with the highest number of traffic violations in Bangkok. In May 2018, CCTV cameras were installed at this and 14 other major intersections known for frequent violations. On just the second day after installation, the cameras recorded 3,524 traffic offenses at this junction alone.
