New Bridge in Santol, La Union Launched to Strengthen Trade and Services

The inauguration of the newly constructed 50-meter bridge Santol–San Gabriel (La Union)–Kapangan (Benguet) Road, La Union in Barangay Mangaan, Santol, La Union on February 14, 2025 marks the launching to strong trade and social services on upland communities and heighten ties between Region 1 and Cordillera Administrative Region.

The bridge, designed to improve transportation and connectivity, features three spans of 15 meters, 20 meters, and 15 meters, supported by two piers and two abutments for enhanced structural stability. The project also includes Portland Cement Concrete (PCC) pavement on the approaches, measuring 52.40 meters (Approach A) and 83.40 meters (Approach B )along with slope protection measures to prevent erosion and ensure long-term durability. The completed bridge is expected to stimulate economic activities in the region by providing a shorter, faster, and more cost-effective transport system not only in the town of Santol and San Gabriel, La Union, but it will play a vital role in strengthening trade and business ties between Ilocos Provinces and Benguet Province, as well as across Regions I and CAR.

Senator Imee R. Marcos who spearheaded the groundbreaking before led the inauguration, which was also attended by Santol Mayor Magno A. Wailan, who initiated the feasibility study for the implementation of the Basic Infrastructure Program (BIP), Construction of Road, Santol–San Gabriel (La Union)–Kapangan (Benguet) Road, La Union (Package 4) (Bridge Component).



Beyond economic benefits, the bridge is also designed to uphold environmental integrity and structural safety, ensuring that development remains sustainable for the years to come.

The completion of this bridge marks another step forward in the government’s efforts to enhance regional infrastructure, improve mobility, and support economic growth. With better road networks and safer passage for residents and businesses, the project is set to make a lasting impact on the development of La Union and surrounding provinces.



With a contract amount of Php 118,799,113.97, the project was implemented by Regional Office I headed by Regional Director Ronnel M. Tan.

Caoayan-Santa Road (Under Construction)

General facts about the proposed Caoayan-Santa Road (based on current available public information)

• In a report by Daily Tribune, District Engineer Reynaldo R. Ablog of the DPWH’s 1st Engineering District said that this infra road project will have a length of approximately 2 kilometers and is part of the DPWH Regional Office’s Multi-Year Program.

• This road will directly connect mainland Santa to mainland Caoayan crossing the Abra River starting from Brgy Rancho. A bridge will connect Brgy Rancho's host island to another island (Puro island). Puro island is composed on three barangays. The road will run through Barangays Puro (Caoayan), Dammay (Santa), and Oribi (Santa). From Oribi Santa, a bridge will span another section of the Abra River all the way to mainland Caoayan town via Pantay Tamurong. See theoretical diagram below for visual learning. The status of this proposed project is subject to change. I will update this post once new information is released.

From the Insiders

On 2025-February-16, we received a message from a project insider correcting a prior statement that the road project would cost 1.1 Billion pesos. It was clarified that the 1.1 Billion-peso fund is for the bridge components only.

Editorial Section

2025-Feb-02 » If this project will push through, the economic, panoramic, and socio-cultural landscape of the mouth at the Abra River will dramatically change. The communities at the mouth of the Abra River are considered "isolated" and far-flung in Ilocos context. There are 6 barangays in ILocos Sur that are situated in the middle of the Abra River.

With the coming of a new road, economic change will become dramatic. The island barangays that will benefit from this project will have improved logistics. Usually, transporting their catch from the sea is arduous. They still need to ride a boat to reach the mainland Ilocos Sur. With this project, trade and commerce will become much easier, more convenient, and safer.

Businesses will fluorish on these islands, since the cost for logistics and transport of goods will become cheaper. Tourism may also grow. The mouth of the Abra River used to be a wild and isolated landscape that is relatively harder to access from mainland Ilocos. The road construction will change the toursim landscape (for the better) in this part of Ilocos.
