The Trinity Bridge in St. Petersburg officially reopened on May 31 after undergoing extensive repairs. The project, which included replacing the road surface, expansion joints, and tram rails, was completed in under four months.

City authorities prioritized the reopening to accommodate major summer events such as the St. Petersburg International Economic Forum, the Scarlet Sails festival, and Navy Day.

The bridge had been in dire need of repair due to potholes, worn joints, and rail wear, according to the Transport Committee and Mostotrest. The last replacement of expansion joints occurred in 2002, while the road surface was last updated in 2018. Typically, the Trinity Bridge handles up to 30,000 vehicles daily.

The renovation commenced in late February 2025, initially with partial traffic restrictions. To expedite the process, the bridge was fully closed to cars from April 1, while maintaining public transport and pedestrian access. The original completion date was set for June 10, with the contract stipulating completion by October.

Workers completed the project ahead of schedule, finishing by May 31. Modern materials were utilized during the renovation, including thermo-hardened tram rails with a rubber profile designed to enhance speed, smoothness, and noise reduction. Special cast asphalt was also employed in the tram track area to create a durable, elastic, and waterproof coating.

The state contract for the replacement of asphalt concrete pavement and tram tracks on the Trinity Bridge amounted to 411.8 million rubles.

On May 29, the Trinity Bridge celebrated its 122nd anniversary. The bridge is known for hosting St. Petersburg’s most picturesque tram route, number 3, which passes by the city’s main attractions. Tram service on the bridge began in 1908, was suspended in 2006, and resumed in 2016.

Several other bridges in St. Petersburg are also scheduled for repairs this year, including Dvortsovy, Blagoveshchensky, Anichkov, Kazansky, and Zeleny.
