Izmailovsky bridge, Regional heritage bridge in central Saint Petersburg, Russia

Izmailovsky Bridge is a three-span stone arch bridge over the Fontanka River, linking Voznesensky Prospekt with Izmailovsky Prospekt. Its side spans rest on box vaults, the middle span on a brick vault, and the whole is covered by a reinforced concrete slab. The arch facades and piers are clad in granite, with triangular cutwaters below and a forged metal railing ending in granite parapets. The bridge is skewed at 65 degrees and measures 70.5 m long and 15.9 m wide.

A wooden crossing existed here by 1753, and the stone bridge was built around 1786–1788 as one of seven standard Fontanka bridges, probably to a design by the French engineer J.-R. Perronet. In 1861 engineer V. V. Dymman replaced the central draw span with a brick arch and demolished the four granite towers that had housed the lifting chains. A major repair followed in 2006–2008.

The name comes from the Izmailovsky Regiment, whose settlement stood on the left bank of the Fontanka; it has been attached to the bridge since 1746. The crossing links Voznesensky Prospekt with Izmailovsky Prospekt, and four decorative lanterns on cast-iron posts mark the entrances.

The bridge carries four lanes of traffic and pedestrian walkways; sidewalks are separated from the roadway by a granite curb and steel barriers. It links Voznesensky Prospekt with Izmailovsky Prospekt, with Obukhov Bridge upstream and Krasnoarmeysky Bridge downstream. The nearest metro stations are Tekhnologichesky Institut, Sadovaya, Sennaya Ploshchad and Spasskaya. The span is skewed at a 65° angle to the river.

The four granite towers that once held the lifting chains were dismantled in 1861, so nothing on the bridge rises today. During the 2006–2008 overhaul, workers opening the arches found iron tie cables anchoring the masonry.
