They are called Roman triumphal arches such as the Arch of Titus
Triumphal arches were stone arches built by the Romans. They would commemorate either a military victory or a public event. Other cultures took the idea and have built triumphal arches to celebrate their own triumphs.
Cement was used by the Romans to build the colosseum. The Romans invented cement and the material they invented was also water proof which allowed for bridges and fountains to be built.
The Romans did not specifically create any one material to built aqueducts and arches. Their arches were mainly stone, some faced with concrete, depending on the purpose for the arch. The aqueducts were large diameter ceramic pipes. On the above ground aqueducts, these ceramic pipes rode atop the arches and they were the aqueducts in the underground ones. The 10th Legion's ceramic workshop has recently been found in Israel and it shows their ceramic kiln rooms and workrooms.
The Romans did not build aqueducts on top of each other. When the aqueducts had to cross valleys the water conduit was put on top of bridgeworks. When the bridgework needed to be high, the Romans achieved this height by building two or three rows or arches on top of each other. This was done to reach the height and maintain the structural solidity the arched offered. There was only one water conduit at the top. The Romans also tried to keep the gradient of aqueducts slight to avoid the water gathering too much speed.

The Romans built structures called triumphal arches to commemorate their military victories. Triumphal arches were typically decorated with reliefs and inscriptions depicting the conquests and achievements of Roman generals.
The Romans developed the bridge with arches.
The triumphal arches were built in celebration of the victories in battle of the consuls during the Roman Republic (509-27 BC) and emperors during the period of rule by emperors (27 BC-476 AD)

The free-standing arches of Rome were triumphal arches. They were built to celebrate a victory in battle of a military commander or emperor. There were 36 such arches in Rome. The first ones were built during the republican period. Two arches were built by Lucius Steritinus. Scipio Africanus and Quintus Fabius Allobrogicus also built one. In the period of rule by emperors only the emperor was allowed to build a triumphal arch. Only four Roman triumphal arches have survived in the city of Rome: the Arch of Titus (AD 81), the Arch of Septimius Severus (203-205) and the Arch of Gallienus (262) and the Arch of Constantine (312). There is a fifth arch just outside the city: the Arch of Drusus (9 BC) close to the First Mile of the Appian Way and next to the Porta San Sebastiano.
So that there could be gladiator and beast combats, Emperor Titus hosted 100 days of games for the Romans to celebrate the opening of it.
It was a statue of Apollo (Helios) the sun god, which was built to celebrate the freedom of the Rhodians.
Poor Romans were integral part of Roman civilisation. Without the jobs they did Rome would not have built her great buidings, the Colosseum, the circuses, the arches, the theatres and amphitheatres, the villas, the roads, the ports, the aqueducts, and all the other trademarks of Roman civilisation.
In the conquered lands, the Romans built roads, some of which were stone-paved, bridges, ports, dams, aqueducts, sewers, public buildings, public baths, theatres, amphitheatres (arenas for gladiatorial games) circuses (chariot racing tracks) and temples.
