Aloragat Bridge

Aloragat Bridge spans the Aloragat River, on the McArthur Highway between the towns of Binalonan and Pozorrubio,  Pangasinan. The contract for the new Aloragat Bridge and the new approaches was awarded with effectivity of August 31, 2001 and with a contract duration of 15 months, to be completed on November 30, 2002. The bridge structure is 210 m long, comprising seven (7) spans of 30 m, six (6) piers and two (2) abutments.  Four (4) girders AASHTO Type 4 Modified, each 30 m. long were used for each of the seven (7) spans for a total of 28 girders. Each pier rests on deep foundations made by two bored piles with diameter 1700 mm (1.7 m.) and length varying from 39 m. to 41.2 m. Each of the two abutments rests on three piles with diameter 1200 mm (1.2 m.) and 32 m. length. Two dynamic load tests (PDA) were conducted on the bored piles to verify design assumptions.  All piles were tested using PIT (of PDI) pile integrity test to determine pile quality all along pile shafts. Due to the desire of the National Government and DPWH to have the bridge completed earlier than what was contractually stipulated, the Contractor was requested to work using an accelerated program schedule or early completion schedule. Foundation Specialists, inc. was able to substantially complete the project on July 1, 2002, five months ahead of schedule.
