Final answer:
It is true that there are multiple arch bridges built by the Romans 2,000 years ago that are still standing today, exemplified by the Pont du Gard in Nimes, France. The Romans utilized true arches and concrete to create enduring structures.
Step-by-step explanation:
The statement that there are multiple arch bridges standing today that were built 2,000 years ago is True. The innovation of the true arch by the Romans was a significant architectural advancement, allowing for sturdier and more enduring structures. The most telling example of this enduring architecture can be found in the Pont du Gard in Nimes, France, which was built in 16 BCE and has survived to this day.
Roman aqueducts, like the Pont du Gard, showcase not only the functional use of arches for water transport but also their aesthetic appeal. The Romans mastered the use of concrete and true arches, which supported massive structures such as the Colosseum and various aqueducts, many of which have withstood the test of time.
