The local government of Sampaloc and the National Museum led in the unveiling of a monumental marker following the declaration of Puente del Sampaloc as ``important cultural property’’ in Sampaloc, Quezon.
The Sampaloc Bridge can now be lined up with other architectural heritage in the province like Puente de Malagonlong, the longest Spanish-era stone bridge in Quezon.
The other stone bridges considered by the National Museum as National Cultural Treasure in 2011 include Puente de Lakawan, Puente de Mate, Puente de Don Francisco de Asis, Puente de Gibanga, Puente de la Ese, Puente de la Princesa, Puente de Alitao, Puente de Isabel II, Puente de las Despedidas, and Puente de Tumuloy o Bai.
One of them was literally embedded in the new infrastructure project of the government: Puente De la Princesa connects the city of Tayabas and the municipality of Lucban from Spanish occupation in the Philippines till now.
In 2017, the Department of Public Works and Highway (DPWH) started the road widening project that created a wider and elevated concrete road. Many motorists in the past met accidents due to its limited capacity.
