The Department of Public Works and Highways (DPWH) will have to look for a new Secretary to lead them. That's because Mark Villar has officially resigned from his post.

Villar made the announcement during the agency's flag-raising ceremony earlier this week. Initially, he did not state the reason as to why he resigned as the agency's Secretary.

That all changes today when Villar officially filed a certificate of candidacy (COC) to run for Senator. This doesn't come as a surprise since Villar was among the individuals included in the senatorial slate of the PDP-Laban faction led by Department of Energy Secretary Alfonso Cusi. Villar is among four members of President Duterte's cabinet who will run in the 2022 elections.

Mark Villar resigns as DPWH chief to run for senator image

Under his leadership, the DPWH was able to complete several important projects in the last 5 years. These include the completion of the Tarlac-Pangasinan-La Union Expressway (TPLEX) all the way to Rosario, the new Subic Freeport Expressway (SFEX), the toll-free Central Luzon Link Expressway (CLLEX), Estrella-Pantaleon and Kalayaan Bridges, the C-5 South Link Expressway, NAIA Expressway (NAIAX), NLEX Harbor Link, and Laguna Lake Highway.

Villar was also instrumental for the start of big infrastructures projects that include the Cebu-Cordova Link Expressway which is set to open in Q1 of 2022, and the Panguil Bay Bridge project which is currently in the foundation-laying phase. The 3.170-km mega bridge is set to become one of the longest bridges in the country and will connect Tangub City in Misamis Occidental and the municipality of Tubod in Lanao Del Norte.

This is not the first time Mark Villar has held a legislative post. During the 2016 elections, he was elected as a representative of Las Pinas. However, Villar soon resigned after President Duterte appointed him as DPWH Secretary.

With his experience in leading the DPWH, does he have what it takes to become a Senator? And what laws will he propose that could help spur infrastructure development in the country?
