Spanish Colonial Period

During the last few years of the Spanish Government in the islands, a bridge was in the project to span across the Pasig from the district of Santa Cruz at Plaza Goiti (now Plaza Lacson) to the south bank of the river connecting to Calle Arroceros (now Padre Burgos St.).

s were built to low-water mark, when the work ceased.

American Colonial Era

When the American Government took charge, it was decided to complete the work. Proposals for the steelwork were advertised for in June and July, 1900. The bids were opened in August, but owing to an irregularity in the opening of bids, all bids were rejected. The matter was finally settled in October, 1900, by purchasing the bridge offered by the original lowest bidder. In the meanwhile nothing had been done toward starting the work on the piers, abutments and approaches. In October plans and specifications for the abutments, piers and approaches were made, and in the month of November proposals were asked for by advertisement. Rids were opened December 1st. The three bids received were of $95,000.00, $89,542.50, and $53,387.50, all U. S. currency. The lowest bid was accepted. The contract called for the piers and abutments by April l, and of the entire work by June 1, 1901.

This bridge was begun December, 1900. The steel for the work arrived on time in March 1901, but the contractors for the masonry had not set a stone in the piers or abutments. The work was then taken from them and carried on by hired labor.
