Ufa rail bridge across the Belaya River carries double tracked rail lines over the Belaya River. It is located in the city of Ufa, the Republic of Bashkortostan, Russia.[1]

Construction

Construction of the bridge began in 1886 and was completed in 1888. The bridge provided for the passage of trains across the Belaya River in the direction of Ufa, and allowed for further construction of the main railway line up to Chelyabinsk (1892).[2][3]

The span structures of the bridge were designed by Prof. Nikolai Beleloubski in compliance with the rules of 1884. All steelwork elements were manufactured at the famous Votkinsk ironworks (now the Votkinsk Machine Building Plant) in Udmurtia, where starting from 1871, open hearth furnaces began to be widely used for the first time in Russia that allowed to produce rails for the country's railroad network.

When designing the bridge‘s spans, Beleloubski developed and introduced a completely new design: the transverse floor-beams of trusses were hingedly connected to their bottom chords. Such a type of structural support was considered to be ground-breaking in the days of Beleloubski, because it allowed to reduce secondary stresses in trusses. At the Edinburg Exposition 1890, this design received the Gold medal and later came to be known abroad as the "Russian support method".[4]

When the construction of the bridge was completed in 1888, an artificial channel was dug out to straighten the course of the Dyoma River. It begins approximately 100 metres (329 ft) downstream of the present-day highway bridge near the cafe 'Goldfish', and runs towards the Belaya directly. The river channel was straightened in order to avoid a construction of another railway bridge across the Dyoma. The fact is that the Dyoma river formerly emptied itself into the Belaya a few kilometres downstream, into its present oxbow lake, which had been the main bed until 1854. The present-day course of the Belaya, which now girdles about Nizhegorodka (the Lower city) was then a wide duct, exceedingly low, in fact fordable in many places. The area that surrounds now Kozorez village was a big island then.

The official opening of the bridge to the public, September 8, 1888.

On 8 September 1888, the bridge was solemnly opened to traffic by Minister of Railway Transport, admiral Konstantin Posyet. A pedestrian path was immediately opened on the bridge. For this purpose, special foot sidewalks were made of wood (subsequently the movement of pedestrians was forbidden).

The bridge‘s superstructure system consisted of 6 spans, each 109 metres (358,432 ft) long. Each of the bridge‘s pillars was equipped with a wedge-shaped cutwater on the upstream side dressed with granite slabs and designed to break up the current of the river and ice-blocks.[5][6]

In June 1919, the battles of the Russian Civil War took place directly around the town of Ufa. Striving to keep their control over the town at any cost, the retreating troops of Admiral Kolchak detonated the sixth right-bank span of the bridge. One end of the truss fell into the river and was strongly deformed. But this didn't help the Whites to manage their goal, because the famous 25th Rifle Division of Chapaev captured the town on 9 June 1919.

With the retreat of Kolchak in Siberia, the assault troops of the Red Army advanced further, while their rear units remained near Ufa on the other bank of the Belaya.

Meanwhile, the crossing was in urgent need of rehabilitation. Since there were no adequate facilities or equipment available, manual labor was the only hope. It was decided to use winches to raise the fallen truss back into place. Inch by inch, step by step. Perhaps this is how the heavy stones were raised to the height of the rising pyramids of Egypt. But nobody seemed to care about the times of Antiquity.

The restoration works involved approximately 2,500 builders, workers and railway engineers. Day by day, week after week made their work. And the iron mass of the bridge buttressed by scaffolds from a beach didn't towered so hopelessly above the Belaya anymore.

As a result of those tremendous efforts, the bridge was successfully restored in that same year through the establishment of the temporary damaged truss followed by a complete overhaul, during which the destroyed one was replaced with a new structure designed by Prof. Lavr Proskouriakov in compliance with the rules of 1907. Proskouriakov designed the largest rail bridges in Russia over the Yenisey and Amur rivers.

Thanks to careful preparation and extraordinary guidance, the bridge builders carried out the replacement of the damaged span with minimal traffic disruption — in just 11 hours. It took 7 hours for pushing the old truss span off the pillars with the use of jacking system, and it took 3 hours 45 minutes for putting a new one in place. On October 10, 1919, Vladimir Lenin sent a congratulatory telegram to the bridge-building crew to express his appreciation for their hardwork.[7]

Renovation

There is an old data sheet of the bridge in the archives of the Ufa City Maintenance of Way, which contains the following entry made in 1928:

"...Trains with double headed E class steam locomotives and american gondola cars are not permitted to cross the bridge, during the passage of single headed E class steam locomotives, the maximum speed shall not exceed 8 km per hour (5 miles per hour)".[8]

In the 20th century, the bridge was strengthened and modified several times. So, in the period 1937-1939, the spans were strengthened with the removal of bulkiness and the addition of new metal with gain up to 4% of their total weight.

In the period 1949-1951, renovation works on the bridge were carried out by the work train №417. Pylons for a second track were erected along the cutwaters of existing pillars (on the upstream side), mounted with span structures constructed to a design by "Proektstalkonstrukciya" of 1943 for Class N7 loading.

The replacement of outdated "tsarist" span structures with advanced ones for S-14 loading was carried out by the open joint-stock company "Transstroymost" during the 1991-2001 period.

Thus, by 2001, all the bridge's spans have been equipped with the contemporary steelwork elements, so there is no need to be concerned about the strength of the structure and safety of the crossing.

Bridge across the Ufa River

Ufa rail bridge across the Ufa River carries double tracked rail lines over the Ufa River. It is also located in the city of Ufa, near the station of Urakovo (Shaksha).

Its design and history were almost the same as the bridge over the Belaya River. It was built and "treated" almost the same 2 years later. It was also designed by Prof. Nikolai Beleloubski in compliance with the rules of 1884, but had only three spans, each 109 metres (358,432 ft) long.

The first color pictures of the rail bridge across the Belaya were taken by Sergey Prokudin-Gorsky in 1910. Photography was carried out by the method of registering on a single glass plate three separate black and white images taken through the blue, green and red filters.[9][10]

During the Civil War in 1919, the third left-bank span of the bridge was blown up by the Kolchak troops, and collapsed. The explosion was carried out by artillery firing on cars with explosives previously established in the span.

In 1920, the destroyed structure was replaced with a new one designed by Prof. Proskouriakov in compliance with the rules of 1907.

In the period 1939-1940, the bridge‘s spans were strengthened with the removal of bulkiness and the addition of new metal with gain up to 4% of their total weight.

In the period 1951-1952, a renovation was carried out on the bridge by the work train №414. Pylons for a second track were erected along the cutwaters of existing pillars (on the upstream side), mounted with span structures constructed to a standardized design by "Ghiprotrans" of 1933 for Class N7 loading.

The replacement of outdated "tsarist" span structures with advanced ones for S-14 loading was carried out by the open joint-stock company "USK MOST" over 2001-2002 period.
