Pochtamtsky Bridge, Suspension footbridge in Admiralteysky District, Russia

Pochtamtsky Bridge is a pedestrian suspension bridge over the Moika River, connecting Kazansky and 2nd Admiralteysky islands. Its single 34-metre span hangs from chains between four cast-iron obelisks topped with gilded spheres, and the cast-iron railing reproduces the original pattern. The bridge is one of the first chain bridges in Saint Petersburg and the only one that still works as a suspension structure.

Built in 1823–1824 to a design by engineer Wilhelm von Traitteur with V. A. Khristianovich, the bridge replaced a wooden beam crossing from the 1790s; its cast-iron parts came from the Berd factory. In 1905 two wooden supports were added after the span kept deforming, leaving the chains and obelisks as decoration. The 1981–1983 reconstruction by Lengiproinzhproekt restored the single-span chain suspension, with chains forged at the Kanonersky plant.

The name comes from the nearby Main Post Office, and the bridge was first listed officially as the Little Chain Bridge over the Moika. In 1956 a copy of the original railing was cast at the tram depot named after Kalinin, using a model made by architect A. L. Rotach from the original drawing. The gilded spheres on the cast-iron obelisks were regilded in 1968 and 1992.

The bridge stands in the line of Prachechny Lane, where it meets the Moika embankment opposite house No. 61 on Bolshaya Morskaya Street. It is pedestrian-only, so cross on foot; the nearest upstream crossing is Fonarny Bridge and the nearest downstream one is Poteshny (Kiss) Bridge. Yusupov Palace at Moika embankment 94 and the house of architect Auguste Montferrand at No. 86 are a short walk along the embankment.

The bridge keeps its original 1823–1824 chain scheme, unlike the Bank and Lions bridges, where the chains are decorative and the spans actually rest on beams. Its 34-metre span is about one and a half times that of those two. Cast-iron turnstiles once regulated pedestrians on the shaking deck.
