Pai Memorial Bridge

The Tha Pai Memorial Bridge spans the Pai River at kilometre marker 88 on Highway 1095, roughly 9 km south of Pai town. Its steel frame came from Chiang Mai’s Nawarat Bridge, decommissioned around 1965 when Chiang Mai replaced it with a concrete span, and transported here in 1975–76. The wooden planks underfoot are replacements, but the green-painted steel truss is original Nawarat ironwork — none of it dates to the Japanese occupation itself, though the site does.

During the Second World War, Japanese forces used this river crossing as part of their supply line toward Burma. The original timber bridge, built with elephants dragging logs from the surrounding jungle and local labour pressed into service, was torched by retreating Japanese troops in 1944 after the Imphal campaign collapsed. Villagers rebuilt a wooden crossing after the war, which was then washed out by severe flooding in 1973 — prompting the government to relocate the Nawarat steel structure as a replacement. A modern concrete road bridge carries vehicle traffic alongside it; the memorial span is foot-traffic only.

As a stop, it takes fifteen minutes. Walk the span, look down at the Pai River, and note the water level: in the dry season (November–April) the riverbed is mostly exposed; by August the water climbs well up the concrete piers. The wooden deck has gaps and some boards flex noticeably underfoot, so watch your step. A local performer sometimes works the bridge in pirate costume charging for photos — a tourist fixture you can politely decline.

Insider Tip: Come at dawn before the tour minivans from Pai fill the roadside car park. The light hits the green steel from the east and the river is calm. By 10 am it is a photo queue.

Watch out: Some planks on the wooden deck have visible gaps or are loose. Take care with footing, especially if it has rained recently.
