Krungthep Bridge
Bangkok's third Chao Phraya crossing is a bascule drawbridge — the same counterweighted lifting design as a classic movable span, planted on the Chao Phraya river in Bangkok.

Only the third bridge ever built across the Chao Phraya, Krungthep was erected by Fuji Car Manufacturing Co., Ltd for 31.9 million baht. It drew so much traffic that an entire 6-lane bridge — Rama III — had to be built nearby just to absorb the overflow. That congestion story is written in steel on both sides of the water.
What to look for
- The bascule mechanism: the counterweighted lifting sections that classify this as a drawbridge, not an ordinary fixed span
- The Chao Phraya itself beneath the deck — the river this was only the third structure to bridge
- The Rama III Bridge close by, six lanes wide, built as a direct consequence of Krungthep's congestion
Approach from the riverbanks to compare both bridges side by side; no admission required to view the structure.
