History
The Ponte Romano di Solestà is a Roman bridge in Ascoli Piceno, Italy, built around 25 BC during the Augustan period, the rule of Augustus, Rome’s first emperor. Spanning the Tronto River, it reflects the city’s growing importance beside the Via Salaria, an ancient consular road linking Rome with the Adriatic region and developed as a major route under the consul Gnaeus Pompeius Strabo. Its designer is unknown.
Roman construction and repairs
The bridge was repaired during the Roman period. Where stones had fallen, fragments of Doric friezes were inserted into the fabric, leaving evidence of later work carried out within the ancient structure.
Modern consolidation and continued use
Conservation campaigns took place in 1929–1930 and 1937–1938. The most consequential intervention was completed in 1938 by the Ascoli engineer G. Viccei during celebrations of the bimillennium of Augustus. The inner travertine blocks were removed and replaced internally with a reinforced-concrete structure. This concealed support was designed to preserve the surviving Roman fabric and withstand vibrations from motor traffic, while leaving the visible ancient exterior intact.
A commemorative stone records the internal reinforcement and carries a Latin inscription dated 1939. On 25 July 1943, the date and fasces symbol were erased from the stone, and Ascoli’s coat of arms was substituted. The fasces, a bundle of rods, carried political and governmental symbolism in ancient Rome and later in Fascist Italy.
The bridge remains a road connection between Ascoli Piceno’s city centre and the Porta Cappuccina district. At its southern end, the medieval Porta Solestà gave access through the former city walls to the San Giacomo district. Its archaeological value and preserved Roman constructional characteristics have made it a representative surviving example of Roman bridge engineering.
Remains
Bridge structure and arch
The bridge is a single-span structure with one monumental semicircular arch crossing the Tronto between recessed riverbanks. It measures 62 metres in length, reaches 25 metres in height at road level, and is 6.50 metres wide, including 5.50 metres of usable roadway. The arch spans 22.20 metres.
Travertine, a durable limestone, forms the bridge’s squared-stone masonry. The regularly cut blocks create horizontal courses of uniform height, with vertical joints positioned over the solid centres of the stones below. A plinth 5 metres above the waterline supports pilasters set against rocky spurs. The pilasters lack bases and are crowned by Doric capitals.
A 20-centimetre-high band with an architrave follows the pilasters and marks the point where the arch begins. The arch has a radius of 10.70 metres. Its opening is defined by voussoirs, wedge-shaped stones forming an arch, each made from a single block. A projecting cornice follows the entire curve, combining a curved moulding with a narrow fillet, and measures 1.80 metres in overall height. A further horizontal band marks the roadway level.
Interior construction and roadway layers
Inspection spaces lie within the piers, together with a passage extending from one riverbank to the other. The inspection corridor is entered from the external eastern end through the door of the building adjoining the bridge. This interior access exposes the original technique: the travertine blocks were laid without mortar and held together by the compression of the arch.
The passage also reveals successive layers of roadway paving accumulated over the centuries. Excavation uncovered several superimposed road surfaces, including Roman paving made from travertine. The ancient surface retains visible wheel-rut marks.
Reinforced internal support
The modern reinforced-concrete structure inserted inside the Roman shell cannot be seen from outside the bridge. It supports the surrounding ancient masonry and absorbs vibrations produced by motor traffic, allowing the original visible travertine architecture to remain externally intact.
Eighteenth-century votive shrine
At the end of the bridge roadway, on the wall of a private house facing the small square before the Sant’Emidio spring, stands an eighteenth-century votive shrine. Its single niche contains a fresco of the Holy Family framed by two caryatids, sculpted human figures used as architectural supports. Two putti, childlike decorative figures, sit above the arch and support a coat of arms. Sant’Emidio is the patron saint of Ascoli Piceno.
