Ponte delle Chianche, Roman bridge in Buonalbergo, Italy.

Ponte delle Chianche is a Roman bridge spanning roughly 120 meters across the Miscano Valley near Buonalbergo. Three of its original arches still stand, while one arch was reconstructed during restoration work carried out between 1986 and 1992.

The bridge was built around 109 CE under Trajan as part of the Via Traiana, the road from Benevento to Brindisi. Its presence, along with other bridges of similar construction, supports the view that the Forum Novum–Herdonia stretch was built new rather than following the Via Minucia. A nearby plaque recorded diking works by Septimius Severus and Caracalla in 210, though the bridge shows no repairs from that time.

The bridge served as part of a mule track used by local farmers to move goods across the valley for generations. This everyday role shaped how people lived with and maintained the structure over time.

The route to the bridge follows rural roads through the valley, so having a vehicle is helpful for a visit. Daytime hours are best for viewing, as the structure becomes clearly visible and can be observed from different angles along the banks.

The arch spans are uneven and foundations sit at different levels, showing how Roman engineers adapted the structure to the sloping terrain. This unconventional solution allowed the bridge to survive for nearly 2000 years without major collapse.
