The Puente Blanco (English: White Bridge) is a historic railway bridge that spans hundred and fifty feet deep and thirty six metres wide gorge across the Quebrada Mala Canyon, near Quebradillas, Puerto Rico.

[2] It was built in 1922 by the American Railroad Company to replace a 1907 steel bridge as part of the construction of the national railway system that connected the island during the first half of the twentieth century.

It was built on a concrete platform that held the existing steel bridge without interrupting the passage of the railway.
