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.

Famous quotes containing the word note:
“The note of the white-throated sparrow, a very inspiriting but almost wiry sound, was first heard in the morning, and with this all the woods rang. This was the prevailing bird in the northern part of Maine. The forest generally was alive with them at this season, and they were proportionally numerous and musical about Bangor. They evidently breed in that State.”
—Henry David Thoreau (1817–1862)
