Twin bridges are independent structures and each bridge has its own superstructure, substructure, and foundation.

While most twin-span bridges consist of two identical bridges, this is not always the case.
In the Book of Revelation, the two witnesses are two of God's prophets who are seen by John of Patmos, during the "Second woe" recorded in Revelation 11:1-14. They have been variously identified by theologians as two people, as two groups of people, or as two concepts. Dispensationalist Christians believe that the events described in the Book of Revelation will occur before and during the Second Coming. The two witnesses are never identified in the Christian Bible. Some believe they are Enoch and Elijah. as in the Gospel of Nicodemus, since they are the only two that did not see death as required by the Scriptures. Others believe them to be Moses and Elijah because they appeared during the transfiguration of Jesus, or because Enoch was not Abraham's descendant. Some also believe that they are Moses and Elijah due to the description of what they are to do. They have the power to shut the heavens (Elijah) and turn water into blood (Moses)

The Narentines were a South Slavic tribe that occupied an area of southern Dalmatia centered at the river Neretva, active in the 9th and 10th centuries, noted as pirates on the Adriatic. Named Narentani in Venetian sources, Greek sources call them Paganoi, "pagans", as they were for long pagan, in a time when neighbouring tribes were Christianized. The tribe were fierce enemies of the Republic of Venice, having attacked Venetian merchants and clergy passing on the Adriatic, and even raided close to Venice itself, as well as defeated the Doge several times. Venetian–Narentine peace treaties did not last long, as the Narentines quickly returned to piracy. They were finally defeated in a Venetian crackdown at the turn of the 10th century and disappeared from sources by the 11th century.
