Segura Bridge is a Roman bridge connecting Segura, in Idanha-a-Nova, Portugal, to the Spanish municipality of Alcántara. The bridge was built over the Erges river, a tributary of the Tagus. It has five arches; only two of the original Roman arches, the ones closer to both river banks, survive to this day, with the rest being added during reconstructions in the 16th and 19th centuries. The stonemason work done during the 1571 reconstruction of two of the arches is considered to be "barely distinguishable" from the original.

The Malpaso Dam, officially known as the Nezahualcóyotl Dam, is located in the Centro region of Chiapas, Mexico near the border with Tabasco and Veracruz. It was the first of several major dams built on the Grijalva River to generate hydroelectric energy and has the second largest reservoir in Mexico, after the Belisario Dominguez Dam. Construction of the dam occurred in the 1960s and flooded not only the riverbed but also hectares of rainforest and farmland, various towns and villages and archeological sites. These include the former town of Quechula, whose 16th century Dominican church will appear when water is at low levels, and the archeological site of San Isidro which contains one of only two known double Mesoamerican ball courts. Commissioning of the dam's 1,080 MW power station began in 1969 and ended in 1977. The reservoir and later construction of a federal highway has spurred ecotourism in the area.

In 1953, the Puerto Rico Department of Transportation and Public Works implemented a major renumbering of its insular highways. Before 1953, highway routes were numbered in the 1 to just over 100 range and were distributed randomly throughout the island, resulting in several routes with long road lengths. The numbering system adopted in 1953, which is in use today, increased the range of route numbers from the just-over-100 to 999, resulting in a decrease in the length of many routes. This new numbering system follows a grid pattern for highways numbered between 100 and 999, with the lower numbered roads found to the west and systematically increasing towards 999 as the traveler moves easterly. Although PR-1, PR-2 and PR-3 routes had notable changes in some of their segments, these three are the only highways that kept their route numbers intact due to their interregional prominence.
