Ufa Rail Bridge
History
Design
The origins of the bridge are closely associated with that of the Trans-Siberian Railway, for which the structure was built for. Construction of the bridge occurred between 1886 and 1888, having been built at the same time as several other railway bridges on the line, including three-span bridge across the River Ufa, east of Ufa. The construction of both bridges was overseen by civil engineer Professor Nikolai Belelubsky, who followed the specifications outlined in the 1884 edition for steel railway bridges. Due to this adherence to the same design standards, these two bridges shared similar features. The completion of these bridges played a pivotal role in facilitating the further extension of the Trans-Siberian line towards the eastern direction, ultimately connecting the towns of Zlatoust (in 1890) and Chelyabinsk (in 1892).
For the design of the bridges, Professor Nikolai Belelubsky was called in. Belelubsky's contributions to the field of building materials research were marked by two significant discoveries that had a profound and lasting impact. Firstly, he found that domestically produced cement was just as good as English cement, allowing for a significant cost reduction in bridge construction. Secondly, Belelubsky made groundbreaking progress in understanding the mechanical properties of carbon steel. In 1882, he was the first in Russia to propose the idea of using steel in the construction of railroad bridges. This is because steel for metal bridges had not been yet systematically used in Austria, while in Germany it had been used with caution, in accordance with the technical requirements of the time. Having evaluated the physical and chemical properties of carbon steel, Belelubsky came to the conclusion that, contrary to the opinion of the time, it was a far more reliable material for bridges compared to wrought iron, which was the prevailing choice at the time. His breakthrough allowed him to successfully replace wrought iron with steel in constructing bridges along the four major sections of the Trans-Siberian Railway. The steel specifications developed by Belelubsky served as the foundation for similar specifications that were later adopted internationally.

The bridge superstructure provided originally for six 109-meter (358 ft.) bowstring arch through truss spans over the river channel, with steel box girders. The design required meticulous alignment of the top and floor elements, known as cords, as well as the inter-cord elements, which are the web elements. These elements were all manufactured using open-hearth steel and were produced at the Votkinsk ironworks, which is now known as the Votkinsk Machine Building Plant located in Udmurtia. This ironworks had been utilizing open hearth furnaces since 1871, allowing to produce railway rails for the country's railway network.

Additionally, Belelubski introduced a ground-breaking method called the "free carriageway" that transformed traditional bridge design. This innovative technique involved integrating articulated support for the cross beams of the travel surface directly into the lower chords of trusses within the bridge spans. By doing so, the structural integrity and operational efficiency of the bridge were greatly improved, as it effectively lessened the pressure on the truss components. The success and recognition of this design were solidified when it was awarded the prestigious Gold medal at the Edinburg Exposition in 1890. The system's functional features captured immediate attention, eventually earning global recognition as the "Russian type of structural support".
The bridge's superstructure was placed on masonry piers that were reinforced by triangular buttresses, also known as cutwaters, located upstream. These buttresses served the purpose of breaking up the ice that flows downstream during the spring season. It is important to mention that the clearance above the average high water level was approximately 17 meters (or 56 feet).
The bridge was officially opened to traffic on 8 September 1888 by Admiral Konstantin Posyet, Minister of Railway Transport. Along with trains, a pedestrian path was added to the bridge, complete with wooden sidewalks for safety. However, pedestrian access was later restricted.
Bridge during the Civil War
During the events of the Russian Civil War in June 1919, the town of Ufa became a central point of conflict, as Admiral Kolchak's forces, battered and desperate, made a strategic retreat from the area, resorting to the detonation of the sixth (right-bank) section of the bridge in a bid to slow down their pursuers. The destructive act was orchestrated with precision artillery fire on railcars laden with explosives placed on the span, causing it to be knocked off from its piers and collapse into the river, resulting in substantial destruction. However, the Whites' efforts were thwarted as the town was ultimately liberated by the renowned 25th Rifle Division of Chapaev on June 9, 1919.

The liberation of Ufa played a crucial role in the ongoing advancement of the forward detachments of the Red Army towards Siberia. To ensure a strategic position, the rear detachments of the Red Army made the decision to establish their presence near the bridge, on the right bank of the Belaya River, adjacent to Ufa. In the meantime, the crossing was in urgent need of rehabilitation. Due to a shortage of materials, the 'rehab job' experienced a significant delay. Additionally, there was a lack of appropriate construction equipment, leaving manual labor as the only option. To overcome this challenge, the decision was made to use scaffolds for putting the fallen truss back into place. In a manner that mirrored the efforts of the ancient Egyptians who transported stones from the earth to the summits of their pyramids, progress unfolded slowly and steadily. Yet, those involved in the work process showed no interest in the Pharaonic era.
The restoration of the bridge required the efforts of a significant workforce consisting of around 2,500 construction workers and railway engineers. As days and weeks went by, the structure gradually ceased to tower above the river in a state of desperation. In order to maintain traffic flow, the compromised truss was repaired and temporarily installed. However, this was only a short-term solution as a complete overhaul was required. During this extensive renovation process, the damaged truss was substituted with a brand-new one, designed by Prof. Lavr Proskouriakov who followed the specifications provided in the 1907 edition. Proskouriakov designed many noteworthy landmark bridges in the Russian Empire, such as those spanning the mighty Yenisey and Amur rivers.
Due to thorough planning and preparations, the crews were able to efficiently replace the compromised section of the bridge, causing minimal inconvenience to the flow of traffic, all accomplished within a remarkably short span of 11 hours. This intricate procedure involved a series of tasks, starting with the 7-hour endeavor of jacking the old span off the piers, followed by erecting the new truss that took 3 hours and 45 minutes.
The remarkable efficiency of the entire operation did not go unnoticed, as Vladimir Lenin himself, on the memorable day of October 10, 1919, took the time to send a congratulatory telegram to the diligent workers responsible for the rehabilitation project, expressing his gratitude for their tireless efforts and dedication to their craft.
Renovation
In the archives of the Ufa Permanent Way Department, a historical document dating back to 1928 provides valuable insight into the bridge's limitations. According to this information note, it is stated that the bridge's structural integrity cannot support the weight of powerful trains equipped with double-headed 0-10-0 locomotives and American gondola cars. The cautionary message goes on to advise that even when a single 0-10-0 locomotive needs to traverse the bridge, extreme care must be taken, necessitating a significantly reduced speed of a mere 8 km/h (5 mph).
Over the span of the 20th century, the bridge experienced several transformations and upgrades in order to meet the ever-changing demands of traffic. In particular, between 1937 and 1939, considerable efforts were dedicated to bolstering the bridge's overall strength and stability. These measures involved the removal of oversized dimensions that had the potential to compromise its structural integrity, as well as the incorporation of reinforcement metal that accounted for approximately 4% of the trusses' total weight.
Between 1949 and 1951, the bridge underwent a significant transformation to accommodate double-track usage. The responsibility of reconstructing the bridge fell upon the construction train with the number 417. The bridge’s piers were remodeled by constructing reinforced concrete supports, known as pylons, on the foundations of the outdated cutwaters, which no longer made sense, and on them a new superstructure was erected, composed of standardized trusses fabricated under Proektstalkonstruktsia specifications of 1943 edition for loads of Class N-7.
From 1991 to 2001, the bridge underwent additional structural repairs, as it had started to show signs of aging. The original superstructure, which was not built to handle the demands of the time, was replaced with a brand-new one, comprised standardized trusses that were engineered to withstand loads of Class S-14. Initially designed to support smaller engines and light railcars, the old superstructure was deemed inadequate for the heavier traffic and larger loads of modern times. The responsibility for the bridge's renovation fell upon the open joint-stock company Transtroymost that served as the main contractor for the project. As a result of these extensive repairs, there is currently no need for concern regarding the stability of the structure or the safety of crossing the bridge, as all of the aging components have been completely replaced.
Bridge across the River Ufa
The Ufa river rail bridge is a bridge that spans over the Ufa River, carrying double tracked rail lines. Situated in the town of Ufa, the bridge is located near the station of Shaksha. Its design and history share many similarities with the bridge that crosses the Belaya River. Like its counterpart, the Ufa river rail bridge was also designed by Prof. Nikolai Belelubsky based on the specifications outlined in the 1884 edition. However, this particular bridge consists of only three spans, each measuring 109 metres (358,432 ft) long in length.

During the tumultuous period of the Civil War in 1919, a significant event occurred when the 3rd left-bank span of the bridge was targeted and subsequently demolished by the retreating troops led by Admiral Kolchak. However, the resilient spirit of reconstruction prevailed, and in the following year of 1920, a brand-new truss was installed to replace the damaged component. This was designed by Prof. Proskouriakov who followed the specifications provided in the 1907 edition.
During the period spanning from 1939 to 1940, various measures were undertaken to enhance the bridge's structural integrity. These measures included reinforcing the bridge with additional metal, removing large dimensions that could potentially compromise its stability, and incorporating reinforcing metal that accounted for approximately 4% of the truss weight.
Between 1951 and 1952, the bridge underwent a significant transformation to accommodate double-track usage. The responsibility of reconstructing the bridge fell upon the construction train with the number 414. The process involved remodeling the piers by constructing of reinforced concrete supports called pylons. These pylons were built on the foundations where the outdated cutwaters used to be, as they were no longer relevant. Upon these newly built supports, a brand-new superstructure was erected, which was made up of standardized trusses that were manufactured in accordance with the Ghiprotrans Institute's 1931 edition specifications, designed to handle loads of Class N-7.
During the period from 2001 to 2002, the superstructure that was deemed outdated underwent a complete replacement with a brand-new structure featuring standardized trusses specifically designed to withstand heavy loads categorized under Class N-7. The responsibility for carrying out the necessary repairs on the bridge fell upon the contractor, Open Joint-Stock Company USK MOST.
Interesting facts
- The completion of the bridge in 1888 was a significant event for the Dyoma River. To make way for the bridge, a man-made channel was dug, starting 100 meters (329 ft) downstream from the current highway bridge close to the café called "Zolotaya Rybka" (Goldfish). The river's path was artificially adjusted to be straight in order to prevent the need for constructing an additional bridge over the Dyoma river. Interestingly, prior to this alteration, the Dyoma River actually flowed into the Belaya River a few kilometers downstream. This junction took place in what is now an oxbow lake, which was originally the main channel of the Belaya until 1854. However, during a period of heavy flooding in 1854, the Belaya River breached its banks and carved a new path for itself. As a result, the old part of the river was separated from the main channel, creating an oxbow lake. With the new course in place, the river now encircled Nizhegorodka (which in Russian means "lower town"), creating a wide and shallow channel that can be easily crossed in many places. The surrounding area, which now encompasses the village of Kozorez, used to be a large island within this altered river system.
- The first color pictures of the bridge were taken by Sergey Prokudin-Gorsky in 1910. The process of photography was carried out by the method of registering on a single glass plate three separate images taken through the blue, green and red filters.
- There is a small island slightly upstream of the bridge that changes into a peninsula every summer. This peculiar phenomenon can be attributed to a historical event that occurred in the early 1900s, when two barges laden with bread tragically met their demise in these waters. The remnants of the sunken vessels served as a foundation for sediment buildup over time, eventually emerging from beneath the water's depths to manifest as an elevated landmass.
