HistoryEdit

 
2015 rehabilitation of the bridge.

Ayala Bridge was originally two separate timber-built bridges (divided into the "San Miguel" and "Concepcion" sections after each side's point of origin, converging into Isla de la Convalecencia)[a] when it was first built in 1872 by Don Jacobo Zóbel y Zangroniz of Casa Róxas (the present-day Ayala Corporation).

Scarcely 10 years after it was opened to traffic, the bridge's condition had degenerated considerably that in 1899, the "San Miguel" portion collapsed, with "Concepcion" following suit months later. Steel became the main material in 1908, and Ayala Bridge became the first steel bridge in the Philippines. Its current form is attributed to a 1930s reconstruction, when it was decided to unify the bridge in a singular route.

Ayala Bridge was closed to the public in early 2015 to undergo rehabilitation and structural repairs to ensure structural integrity. It was raised by 70 centimeters (28 in), enabling it to withstand a 7.2 magnitude earthquake. The bridge fully reopened to the motorists in November 2015.[4]
