What Roman bridge in Rome, built in 62 BCE, is the oldest still in use?

The Roman bridge in Rome built in 62 BCE and still in use is the Pons Fabricius.

Also called the Ponte Fabricio or Ponte dei Quattro Capi, it crosses part of the Tiber between the Campus Martius and Tiber Island. Lucius Fabricius commissioned it while serving as curator of Rome’s roads, replacing an earlier wooden bridge destroyed by fire. The bridge remains completely intact from Roman antiquity and has carried traffic continuously for centuries.

The Pons Fabricius is about 62 metres long and 5.5 metres wide. Its two broad arches rest on a central pier, and their slightly flattened form reflects Roman adaptation to the river’s conditions. The nickname “Bridge of the Four Heads” comes from two marble pillars decorated with four-faced Janus herms, although those sculptures were moved to the bridge in the medieval period.

The nearby Pons Cestius crosses from Tiber Island toward Trastevere, so it is an easy visual mix-up. The older Pons Aemilius is an earlier Roman stone bridge, but it survives only in fragmentary form and is not the oldest intact bridge still in use.
