Thepsuda Bridge

Thepsuda Bridge is a long concrete bridge spanning the Lam Pao Reservoir in Sahatsakhan District, Kalasin Province, northeastern Thailand. Connecting Sahatsakhan and Nong Kung Si districts, it is one of Thailand's longest bridges over a freshwater reservoir, measuring approximately 2,040 meters. Named in honor of Princess Maha Chakri Sirindhorn, the bridge is a popular scenic viewpoint offering panoramic reservoir views, especially at sunset, and serves as a key local transport link and tourist attraction.

Visitors can expect a long, straight two-lane bridge crossing the wide Lam Pao Reservoir with open water views on both sides, distant hills and small islands. The bridge has pedestrian walkways and viewpoints for stopping, photography and sunset viewing. The surrounding area includes reservoir shoreline, fishing villages, food stalls and parking areas at both ends. Visitors typically drive, cycle or walk across, enjoy the breeze and panoramic scenery, and explore the reservoir banks.

The bridge was constructed to provide a direct connection across the Lam Pao Reservoir, which was created by the Lam Pao Dam completed in 1968. The bridge was named 'Thepsuda' after the royal title of Princess Maha Chakri Sirindhorn and was officially opened in the 2000s to improve transport between Sahatsakhan and Nong Kung Si districts and promote tourism.

The bridge is named in honor of Princess Maha Chakri Sirindhorn and is considered a landmark of Kalasin Province. It is a significant local gathering place for festivals, sunset viewing and community activities, and symbolizes development and connectivity for communities around Lam Pao Reservoir.
