Kamenny Bridge in Tomsk, Stone bridge in Tomsk, Russia.

Kamenny Bridge is a reinforced-concrete slab bridge over the Ushayka River, 42.2 metres long and 24.4 metres wide, built in 1916 to Konstantin Lygin's design. Its four corners carry rostral columns, with four low four-sided lamp posts set between them. It is Tomsk's only tram bridge.

The reinforced-concrete bridge, designed by Konstantin Lygin and built by engineers Tsezar Lyubinsky and Eduard Vekker, replaced the wooden Duma Bridge of 1819, which had been designed by the future Decembrist Gavriil Batenkov. It first opened on 20 November 1915 but was damaged in the spring 1916 flood, then repaired and finally opened on 20 October 1916. It was Lygin's last building before he devoted himself to teaching at the Tomsk Technological Institute.

The bridge's four corners carry rostral columns, modelled on Roman ship-prow monuments, with four low four-sided lamp posts set between them. Since 1949 the columns have served as supports for the tramway's overhead contact wires, and the bridge remains Tomsk's only tram bridge.

The crossing allows both pedestrian and limited vehicle traffic and operates reliably throughout the year. Visitors should expect ice and snow on the surface during winter months.

The bridge is actually a reinforced-concrete slab structure, not stone-built, despite its name. It is Tomsk's only tram bridge: trams have run across it since 1949, when the rostral columns at its corners were reused as supports for the overhead contact wires.
