Ayusan–Paoa Bridge

The Ayusan–Paoa Bridge is a Spanish colonial era arch bridge in Vigan, Philippines, estimated to be constructed around 1842. It is made of mud bricks, and a mixture of lime and eggs as mortar. The Department of Public Works and Highways (DPWH) proposed the demolition of the bridge in 2015 and the construction of a new bridge in lieu of it. Such plan was opposed by various local groups and the proposed bridge was built beside the old bridge instead. It is recognized as a National Cultural Treasure in 2016.
