Trucks weighing more than 15 tons are prohibited to cross Buntun Bridge in Tuguegarao City, Cagayan, the Department of Public Works and Highways (DPWH) announced Thursday.

The DPWH made the announcement as the bridge is "already showing signs of deterioration, as manifested in the continuous appearance of openings on the deck slab."

"Relative to this, heavy trucks weighing more than 15 tons are not allowed to pass over the bridge to prevent any untoward incident," the DPWH said.

"Vehicles weighing more than 15 tons are advised to take the Daang Maharlika route in Isabela when traveling to and from the Province of Cagayan," it added.

Opened in 1969 to vehicular traffic, Buntun Bridge is a river bridge that stretches from Tuguegarao City to Solana, Cagayan and spans the Cagayan River, the largest basin in the Philippines.

In 2023, the DPWH allotted a P101.3 million budget for the retrofitting and strengthening of the bridge.
