Krung Thon Bridge

Krung Thon Bridge is a road bridge that spans the Chao Phraya River connecting Dusit and Bang Phlat districts. The structure features four traffic lanes, pedestrian paths on both sides, and a steel superstructure supported by concrete piers.

Construction of the bridge began in 1954 and it opened in 1958 following completion by a Japanese manufacturing firm. The project marked a significant step in expanding infrastructure across the Chao Phraya River in Bangkok.

The structure carries the alternative name Sang Hi Bridge, derived from the former name of Ratchawithi Road, reflecting local naming traditions. This name remains in use among residents today and connects the bridge to the street's past.

The bridge offers four traffic lanes and wide pedestrian paths on both sides for safe crossing. Visitors should note the crossing is heavily used during rush hours, particularly in early mornings and evenings when congestion is heaviest.

The bridge was the second crossing constructed over the Chao Phraya River in Bangkok and played a key role in reshaping city infrastructure. Many residents use it daily without realizing it marks such an important milestone in the city's development.
