Bang Rak District contains some highly developed areas. Commercial development is most concentrated around Si Lom and Sathon roads, while the areas towards Maha Phruettharam are quieter and mostly residential. Development also fronts Rama IV Road, especially around the neighbourhoods surrounding its intersections: Saphan Lueang (where it is met by Banthat Thong Road in Pathum Wan District), Sam Yan (where Si Phraya Road meets Phaya Thai), Henri Dunant (Surawong and Henri Dunant), Sala Daeng (Si Lom and Ratchadamri), and Witthayu (Sathon and Witthayu).
