Ponte Sisto

Roma Capitale states that Sixtus IV della Rovere (1471-1484) built it for the Jubilee of 1475 to allow direct communication between the rione Trastevere - and the Vatican - and the rest of the city, and records that at the time only the Tiber Island bridges and Ponte Sant'Angelo were working. it.wikipedia gives the construction dates as 1473-1479 and places the bridge in the rioni Regola and Trastevere, with a length of 108 metres and a width of 11 metres. The two date framings are recorded as each source gives them and are not merged. The designer is unresolved: Roma Capitale records that the Vasarian attribution to Baccio Pontelli (c. 1450-1492) has fallen, because Pontelli reached Rome only after construction, and it.wikipedia's infobox itself reads 'Baccio Pontelli (?)'. In 1877 two suspended metal walkways were added to a design by Angelo Vescovali (1826-1895); after a debate running from 1977 to 1998, a restoration by Gaetano Miarelli Mariani removed the nineteenth-century metalwork and rebuilt the parapets. Sixtus IV's two plaques were removed for museum conservation.
