Source-derived summary

Puente de las Calabazas is a single-span lattice girder bridge over the Cuyón River near Coamo, Puerto Rico on the Carreterra Central that dates from 1882. It was designed by Ricardo (or Raimundo?) Camprubi and was fabricated by Eugen Rollin and Co., a Belgian firm that exported via Spain from Braine le Comte, Belgium. Prolific engineer Camprubí designed several single span lattice bridges in Puerto Rico. He also designed the first two-span lattice girder bridge in Puerto Rico, the Padre Inigo Bridge (in Coamo, No. 174), which is also NRHP-listed. All of these were part of the Carretera Central.

It was listed on the U.S. National Register of Historic Places in 2009.

Why this record matters

A short description can identify a subject without explaining its stakes. For “Puente de las Calabazas”, the useful work is to connect “historic bridge in Coamo, Puerto Rico” to the records capable of establishing context and consequence.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q7258513. Authority coordinates are 18.088, -66.313. None of the 1 selected statements returned an explicit reference.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
