Question: Which medieval stone closed-spandrel segmental arch bridge over the Arno River, in Florence, Italy is situated a short distance from the Palazzo Pitti?
Context: The Stone Arch Bridge is a bridge in Danville, Illinois, which carries U.S. Route 136 (US 136; East Main Street) across Stony Creek.  The segmental arch bridge is 92 ft long and built with sandstone.  The bridge was built in the 1890s to facilitate Danville's expansion during an industrial boom.  As various geographic and political limitations prevented the city from expanding in any directions but east and southeast, the city grew over Stony Creek, necessitating a new bridge.  Mayor John Beard commissioned the bridge; during the 1890s, Beard and political rival John Cannon clashed over many issues, and Beard most likely built the bridge to demonstrate his political effectiveness.  The bridge is the only segmented arch bridge remaining in east-central Illinois and is one of five stone arch bridges in the region. Harrison Avenue Bridge is a concrete deck arch bridge carrying Harrison Avenue (unsigned SR 6011) in Scranton, Pennsylvania, United States.  Its three spans include an open-spandrel ribbed arch over Roaring Brook, flanked by two closed-spandrel arches.  The southwestern closed-spandrel arch spans the former Lackawanna and Wyoming Valley Railroad (Laurel Line), converted to highway use in 1964 as the Central Scranton Expressway.  The northeastern closed-spandrel arch spans the former Delaware, Lackawanna and Western Railroad, now a heritage railroad operated by Steamtown National Historic Site. The Oltrarno is a quarter of Florence, Italy.  The name means "beyond the Arno" (compare to the Roman quarter of Trastevere); it is located south of the River Arno.  It contains part of the historic centre of Florence and many notable sites such as the church Santo Spirito di Firenze, Palazzo Pitti, Belvedere, and Piazzale Michelangelo. The Ponte Vecchio ("Old Bridge", ] ) is a medieval stone closed-spandrel segmental arch bridge over the Arno River, in Florence, Italy, noted for still having shops built along it, as was once common.  Butchers initially occupied the shops; the present tenants are jewelers, art dealers and souvenir sellers.  The Ponte Vecchio's two neighbouring bridges are the Ponte Santa Trinita and the Ponte alle Grazie. Trajan's Bridge (Romanian: "Podul lui Traian" ; Serbian: Трајанов мост, "Trajanov Most" ) or Bridge of Apollodorus over the Danube was a Roman segmental arch bridge, the first bridge to be built over the lower Danube.  Though it was only functional for a few decades, for more than 1,000 years it was the longest arch bridge in both total and span length. The Spring Lake Bridge is a historic bridge in the eastern part of Ozark-St.  Francis National Forest, carrying Highway 35 across an inlet of Spring Lake known as Bob Barnes Branch, in the Spring Lake Recreation Area.  It is a two-span closed-spandrel stone arch bridge with a total length of 36 ft .  Each arch is 10 ft long and 6 ft high.  Built in 1936 with federal funding, it is one of the state's finest examples of a stone arch bridge. The Ponte San Lorenzo is a Roman segmental arch bridge over the river Bacchiglione in Padua, Italy.  Constructed between 47 and 30 BC, it is one of the very earliest segmental arched bridges in the world.  It is also notable for the slenderness of its piers, unsurpassed in antiquity. The Bridge near Seydikemer was a Roman segmental arch bridge near the ancient city of Xanthos in Lycia, in modern-day southwestern Turkey.  Its remains are located on the upper reaches of the Xanthos river ("Koca Çayı"), 4 km upstream from the town of Seydikemer, at a site where the gravel river bed reaches a width of 500 m. Only a 29 m long and 4.5 m wide section on the right river bank, outside of the inundation zone, is left today, having once served as approach to the bridge proper.  Despite its near-complete destruction, the bridge represents a noteworthy example of the early use of segmental arches and hollow chambers in bridge building. The Palazzo Pitti (] ), in English sometimes called the Pitti Palace, is a vast, mainly Renaissance, palace in Florence, Italy.  It is situated on the south side of the River Arno, a short distance from the Ponte Vecchio.  The core of the present palazzo dates from 1458 and was originally the town residence of Luca Pitti, an ambitious Florentine banker. The Vasari Corridor (Italian: "Corridoio Vasariano" ) is an elevated enclosed passageway in Florence, central Italy, which connects the Palazzo Vecchio with the Palazzo Pitti.  Beginning on the south side of the Palazzo Vecchio, it then joins the Uffizi Gallery and leaves on its south side, crossing the Lungarno dei Archibusieri and then following the north bank of the River Arno until it crosses the river at Ponte Vecchio.  At the time of construction, the corridor had to be built around the Torre dei Mannelli, using brackets, because the owners of the tower refused to alter it.  The corridor covers up part of the façade of the Church of Santa Felicita.  The corridor then snakes its way over rows of houses in the Oltrarno district, becoming narrower, to finally join the Palazzo Pitti.  Most of it is closed to visitors.
