Roman bridge of Salamanca

The Roman bridge of Salamanca, also known as Puente Mayor del Tormes is a Roman bridge crossing the Tormes River on the banks of the city of Salamanca, in Castile and León, Spain. The importance of the bridge as a symbol of the city can be seen in the first quartering of city's coat of arms. It has been known traditionally as puente mayor and as puente prinçipal which gives access to the southern part of the city. The bridge as it currently appears is a result of several restorations. One of the disasters that most affected it was the Flood of San Policarpo on the night of January 26, 1626. It was declared Artistic Historic Monument on June 3, 1931, and Bien de Interés Cultural since 1998. Until the beginning of 20th century it carried the main road into the city, and continued to bear heavy traffic until 1973. After the construction of a third bridge for road traffic it remains exclusive for pedestrians.
