The Taelayag Spanish Bridge is a small stone arch over a tributary stream on the inland road south of Agat, dating from the late Spanish colonial period in the 19th century. It is one of a handful of surviving stone bridges from that era on Guam, all of them built to carry the camino real linking the southern villages to Hagåtña. The arch is short, mossy, and easy to miss — it sits below the modern road bridge that has replaced it.
There is no interpretation on site and the bridge has no facilities, but it is included on the National Register of Historic Places and is worth a five-minute stop if you are driving the southern loop. Park briefly, walk down to the streambed, and look at the dressed stonework — a quiet reminder that Guam's Spanish history runs deeper than the war that overshadows the rest.
