List of Historic Civil Engineering Landmarks

The following is a list of Historic Civil Engineering Landmarks as designated by the American Society of Civil Engineers since it began the program in 1964. The designation is granted to projects, structures, and sites in the United States (National Historic Civil Engineering Landmarks) and the rest of the world (International Historic Civil Engineering Landmarks).

As of 2024, there are 235 designated Historic Civil Engineering Landmarks in the United States and 61 internationally, totaling 296 landmarks worldwide.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Sections or chapters of the American Society of Civil Engineers may also designate state or local landmarks within their areas; those landmarks are not listed here.
