Blue Bridge (Saint Petersburg)

The Blue Bridge (Russian: Си́ний мост, Siniy most) is a 97.3-metre-wide (319 ft) bridge that spans the Moika River in Saint Petersburg, Russia.

The Blue Bridge spans the Moika River and is located in front of the Mariinsky Palace at Saint Isaac's Square in city's historic centre.

The first cast iron bridge on the site was designed in 1805 by the architect William Heste,[1] and built in 1818.

In 1842–1844, the bridge was widened on its northern side to its present width of 97.3 metres - just as wide as the adjacent Isaac's Square.

Today, most of the Blue Bridge serves as a parking lot.

The Blue Bridge is the widest bridge in Saint Petersburg.
