by Maritess Beņas
Bangued, Abra (1 May) -- The completion of the Calaba Bridge is a dream-come-true to the people of Abra and brings hope for development as it opens its door to the world.
Using an Austrian modular steel bridge structure, the 900 linear meter long Calaba Bridge along the Abra-Ilocos Norte National Road connects the three municipalities across the Abra River namely La Paz, Danglas and Lagayan to Bangued and the other parts of the province.
More importantly, said bridge serves as a primary link to the provinces of Ilocos Norte and Cagayan and other urban centers in the region where farm produce to the rural areas could be transported. Travel time to Laoag City where the international airport in Northern Luzon is located, will be cut by one hour with the usual route via the province of Ilocos Sur.
Before the construction of the Calaba Bridge, people from the towns across the Abra River reach Bangued only through ferry and fording.
The total cost of this project is P478,730,000.00. The amount is broken down for the two major components - P143,240,000.00 for the steel materials cost, and P335,490,000.00 for the cost of civil works.
Civil works for Phase 1 implemented by the J.H. Pajara Construction Corp had a budget of P177.68 million while Phase II undertaken by the Tokwing Construction amounted to P157.81 million.
The Austrian modular steel bridge structure was designed and materials used were supplied by Waagner Biro Philippines, Inc.

Negotiations for the funding of the construction of the Calaba Bridge date back to the past administration of the province. Conceptualization of the project started in the early part of 2005. During this period, negotiations for the road's Right-of-Way were worked out.
Phase I of the construction started on September 12, 2005 for the substructure with the scope of work covering foundation, columns, wing wall at both abutments. Phase II commenced on March 25, 2008 for the superstructure, approach roads and slope protection works.
