The Kamphaeng Phet provincial administration said the Sri Mongkol Wachiranusorn Bridge across the Ping River linking Tambon Wang Kaem and Tambon Mae Lat in Klong Klung district collapsed at about 50 minutes past midnight.
It collapsed just a day after the provincial administration closed access to the 19-year-old bridge after local residents spotted that one of its pillars had been almost washed away by days of strong currents in the Ping River.
No one was injured in the incident.
In Chai Nat, irrigation officials increased the water discharge from the Chao Phraya Dam to the rate of 1,479 cubic metres per second from 1,200cm at the end of last month, as the water level in the dam was rising fast due to floodwaters flowing in from upstream provinces.
Officials warned residents, who live along the river banks downstream from the dam, to brace themselves for possible overflows.
Som, 40, the driver from Chiang Mai, said he was driving his pickup to deliver pumpkins to a customer in Sakhon Nakhon province at 3am when his truck was washed away from the main road in front of Wat Nong Hoi.
He said the runoff was sudden, as a result he was unable to control his pickup and it was washed off to the roadside. He managed to climbed out and escape before the pickup fell down the roadside.
After the water levels reduced, local villagers helped transfer pumpkins from the pickup to another vehicle to deliver to the customer.
Provincial officials said water had subsided in most of the flooded areas of Sukhothai.
The provincial administration said 11,366 families in 541 villages of 67 tambon from 9 districts in Sukhothai were affected by the recent flooding.
