Komsomolsk-on-Amur road-rail bridge

During the period spanning from June to September in 1932, an important survey was conducted to assess the feasibility of constructing a bridge over the Amur River in the vicinity of the city Komsomolsk-on-Amur.

Their primary objective was to evaluate and propose three potential options for the location of the bridge, specifically addressing whether it should be situated upstream, downstream, or within the city limits, extending all the way to the village of Pivan-1.

Long sleepers were used to lay temporary rails on the frozen surface, effectively spreading the weight of passing wagons.

The grand inauguration of the primary bridge of the Baikal-Amur Mainline took place on 26 September 1975, marking a significant moment in rail transportation history.

Additionally, the bridge design was tailored for use in the Arctic Zone A, taking into account the unique environmental conditions of that area.

To achieve this, the spans of the two-lane highway are cleverly installed on remote brackets, which are positioned downstream in relation to the railway trusses.

Between the years 1970 and 1971, a groundbreaking construction method was implemented by Prof. Konstantin Silin (1913-1996), marking its debut in the realm of domestic bridge building.

Notably, this approach deviated from the conventional use of caissons, which had long been employed in the construction of expansive and road-rail bridges along the Trans-Siberian railway.

The world's first application of the reactive turbo-drilling method in bridge construction involved anchoring ferro-concrete sheaths into bedrocks.

On either side of the bridge, the river banks are fortified with multiple layers of barbed wire, defensive pillboxes, and control towers, forming an impregnable barrier.

To enhance training exercises, certain military units have even constructed a scaled-down replica of the bridge on the left bank, providing a realistic environment for honing their skills and tactics.
