The Blue Bridge in St. Petersburg is one of the oldest in the city. Its construction began in 1791 under the guidance of the famous Petrozavodsk merchant F. Bekrenev and was completed in June 1794. Initially, the bridge was wooden and equipped with a chain drawbridge mechanism. It was originally painted green but was later repainted blue, which gave it its current name.

In 1840, the Kronstadt gauge was attached to the bridge, from which measurements of depths and heights in Russia are taken. The installation of the gauge was proposed by the outstanding hydrographer Mikhail Frantsevich Reineke, who conducted sea level measurements for 15 years. A mark corresponding to the average water level of the Gulf of Finland based on observations from 1825 and 1839 was made on the stone pier of the bridge, but it was lost in 1874 during reconstruction.

The original bridge lasted until 1874, when it was decided to build an iron bridge in its place according to the design of Lieutenant Colonel Petrovsky. The new bridge became a rotating one and had a wooden deck with pedestrian paths. The metal parts were manufactured at the Archimedes factory in St. Petersburg, and the stonework was done by merchant Y. Brunov. Gas lamps were installed by the Kronstadt Gas Plant. Construction was completed in the summer of 1875. Although the bridge was temporarily called "New" and "Customs," the familiar name "Blue" officially stuck.

In the 1960s, the bridge was widened and became reinforced concrete, and it has remained in this form to this day. A memorial plaque commemorating the hydrographic work of Mikhail Frantsevich Reineke is installed on the bridge. Despite the fact that nothing remains of the original appearance of the bridge, it continues to be considered a monument of cultural heritage.
