The Buntun Bridge is the longest river bridge in the country, which stretches from Tuguegarao to Solana Cagayan. Under it is the Majestic Cagayan River which is the largest river basin in the Philippines. The bridge was constructed for the sake of travelers that wanted to cross Cagayan river since it was the bridge that was know s the gateway o the City of Tuguegarao.
The bridge was also known as the second longest in the country except for the Candaba Viaduct of Pampanga which is built in the land. The Buntun Bridge has the total of 15 spans, long enough to carry more that 18 tonnes of vehicles passing through as the passage in and out of the city.
Construction of the 4.6 million-dollar bridge was contracted to the Construction and Development Corporation of the Philippines (now the Philippine National Construction Corporation), which together with Japanese engineers conducted studies and designed the actual project.
The bridge had never been flooded by the Cagayan River but it almost did when the typhoon Ondoy and Juan hit the City. It has been the flood basis of Tuguegarao that when the bridge was flooded, the city is also affected since the height of the bridge is similar to the height of Tuguegarao city.
It is also said that the bridge is long enough for a person to recite the entire Philippine National Anthem.
