1st Engineering Bridge
1st Engineering Bridge over the Moika. The river itself begins under the bridge, branching off from the Fontanka. This bridge is one of a cascade of bridges in the center of imperial St. Petersburg. On one side is the Mikhailovsky Castle - the palace of Emperor Paul, on the other - the famous Summer Garden. The length of the bridge is 27.8 meters, the width is 9.5 meters.

1st Engineering Bridge
The name is associated with the new name of the Mikhailovsky (Engineering) Castle, where the Main Engineering School was located in 1823.
In the 1780s.
A wooden bridge was built here, called the Summer Bridge. In 1828-1830 a new single-span arched metal bridge was built (designed by engineers P. P. Bazin and B. P. E. Clapeyron). The foundations for the coastal abutments were made in the form of a grillage on piles.
The stone supports were lined with granite blocks of clean hew. The metal structures of the bridge were manufactured at the Aleksandrovsky Iron Foundry and at the K. N. Berd plant.
In the second half of the 19th century, the Letniy Bridge was first renamed the Engineering Bridge, then (since 1882) the 1st Engineering Bridge.
The facades of the arches are decorated with applied cast iron castings in the form of antique shields and helmets.
The lanterns are made in the form of bunches of crossed spears, connected in the middle by interlacing wreaths. This design is characterized by increased stability. The lattice of the bridge is made according to the drawing of the architect L. I. Charlemagne and consists of short spears-javelins connected by horizontal rods.
The pillars of the lattice are made in the form of lictor beams; they are equipped with swords and shields with the image of the head of the Gorgon Medusa. In 1946, traffic on the bridge was closed due to subsidence of the supports and progressive deformations of the span.
In 1952-1954, the bridge was completely rebuilt (according to the design of engineer B.B. Levin). Inclined piles were added to the base of the supports.
Instead of the old cast iron arches, the new span uses double-hinged, prestressed frames with a steel crossbar and reinforced concrete legs. The architectural design of the bridge has been restored to its original form. The lanterns were recreated according to the design of the architect A. L. Rotach. In 2002, the bridge was restored again.
