Explanation:

Roman public works had a highly positive effect in the provinces of the Roman Republic and then the Empire. Roads and bridges, for example, made trade much easier for merchants as well as they enabled the Roman legions to mobilize to areas where they were needed in a faster and more efficient way. It is noteworthy to say that Roman builders did not like to build around natural obstacles such as mountains or rivers, so they came up with solutions to build roads as straight as possible, which kept distances between towns  and cities as short as possible. Aqueducts allowed the construction of large cities by providing a steady supply of drinking water and sewage water. As of harbors, Roman engineers invented a special and very useful type of cement called "hydraulic cement" which consisted of volcanic ashes added to regular cement with the property of solidifying quickly underwater. Therefore, harbors such as the artificial harbor of Cesarea, in Palestine, greatly boosted sea trade around the Mediterranean Sea.
