An island province in the Philippines has been placed under a state of calamity as the Department for Public Works and Highways has recommended a major repair to a steel bridge that is its only access to the rest of the nation.

Biliran Bridge, built in 1975, crosses a narrow stretch of sea between Samran Island and Biliran Island, 950 miles south of Manila in Region VIII. Viral video footage from 25 December shows the deck oscillating, amid concerns about its structural integrity and safety.

An inspection by the Regional Office VIII Bridge Expert on 24 December found damage under the deck to stringers, and steel cross bracing. The built-up sections of spans 3 and 4 were also damaged. The inspection also found loose nuts and bolts at span one. The survey concluded that the bearing plates and deck slab were in fair condition. The damage was attributed to saltwater and movement of vehicles.

The inspector has recommended repair or replacement of the damaged components.

Light vehicles can use the crossing one at a time; but heavier cargo will be carried by barge. The provincial and local governments are working together to ensure public safety and reduce disruption to the passage of essential goods and to stabilise costs.
