[It is requested that additional entries should be made on the basis of credible print or online sources. Please provide your sources.] ] Note on classification
Bridges are particularly difficult to classify as they, more than other structures, are subject to wear, war and the impact of natural elements. The constant need for repairs through the ages has often turned bridges into hybrid structures, which make it often difficult or nearly impossible to determine the exact date and origin of individual parts of a bridge. Thus, the majority of the bridges listed below can be assumed to include medieval or (early) modern modifications, replacements or extensions, to a small or large extent.
Masonry bridges
Below bridges out of stone or brick. The vast majority features arches, although stone deck slabs were also known. Concerning the bridges' spans and height: S = small, M = middle and L = large.
Aqueduct bridges
