Bataan-Cavite Interlink Bridge is a cable-stayed bridge being built on Manila Bay, Philippines, to reduce the travel time from Bataan to Cavite from five hours to 40 minutes.

The project is being developed by the Republic of the Philippines’ Department of Public Works and Highways (DPWH) with an estimated investment of $3.6bn. It is a priority project under the government’s Build, Build, Build (BBB) programme that aims to boost the country’s economic growth through increased investments in public infrastructure.

The National Economic Development Authority Board approved the project in January 2020. Bridge construction began in November 2020 and is expected to be completed in January 2022.

The bridge will permanently connect the provinces in Central Luzon and Southern Tagalog region, reducing the travel time and alleviating traffic congestion in Metro Manila.

Bataan-Cavite bridge design and construction

The design of the bridge has been drawn from the sea, surrounding mountains, and Manila’s skyline. The 32.15km-long Bataan-Cavite bridge is being constructed with two lanes in each direction, connecting Bataan and Cavite provinces, located northwest and southwest of the capital Manila.

“The project will involve the construction of two cable-stayed navigation bridges, the North Channel Bridge with a main span of 400m and the South Channel Bridge with a 900m main span.”

The bridge will start at Barangay Alas-asin in Mariveles, Bataan, crossing Manila Bay, and terminating at Barangay Timalan in Naic, Cavite.

The project will involve the construction of two cable-stayed navigation bridges, the North Channel Bridge with a main span of 400m and the South Channel Bridge with a 900m main span, standing at a water depth of approximately 50m. Land viaducts, marine viaducts, and ancillary buildings will also be constructed under the project.

The four-lane cable-stayed bridge will stretch 17km between Cavite and Corregidor and 4km between Bataan and Corregidor and will be the longest bridge in the Philippines.

After reaching Corregidor, the bridge will transition into a tunnel and leave the surface of the historic island, allowing the development of a stopover from the high-speed train for easy access.

Project benefits

The new signature bridge will provide a significant transportation corridor for the Philippines and drive new economic growth for the country. It will ease traffic on the North Luzon Expressway.

The project will help to transform the regional economies of Cavite, Bataan and provinces located further north of Bataan through improved connectivity, new economic opportunities and jobs.

The bridge will also provide opportunities for new expansion and economic growth outside Manila such as the development of seaports in Cavite and Bataan as major international shipping gateways to the Philippines.

Financing for the Bataan-Cavite Interlink Bridge

Asian Development Bank (ADB) approved a $200m loan as additional financing for the Infrastructure Preparation and Innovation Facility for the project in December 2019. It is also preparing to support the financing for the construction of the project in 2022.

Contractors involved in the project

A joint venture of the US-based T.Y. Lin International and the Republic of Korea’s Pyunghwa Engineering Consultants, along with the Philippines’ DCCD Engineering Corporation and Switzerland-based Renardet received the contract for the project.

DPWH signed a $59m deal with the contractors for the detailed engineering design (DED) of the bridge project in October 2020.

Ove Arup & Partners Hong Kong has been appointed as consultant for DPWH for this project. Arup officially commissioned the Maritime Academy of Asia and the Pacific (MAAP) for the design, development, and execution of the required simulation exercises to understand the manoeuvrability of simulated vessels along the proposed navigation channel beneath the bridge.
