Russia achieved a monumental milestone with the inauguration of its first aluminium road bridge, spanning the Linda River along the Tolokontsevo – Mogiltsy motorway in Bor. Notably, the 72-meter-long structure stands as an innovative venture for both the aluminium and construction industries, being entirely composed of aluminium alloys—a groundbreaking feat previously unexplored in Russian bridge engineering.

Comprising four aluminium spans, each 18 meters long, the bridge utilized plates ranging from 25 to 42 millimeters in width, employing 1565Чм and 6082T6 aluminium alloys—a testament to its capacity to withstand substantial operational loads. The construction involved the unique friction stir welding method, consolidating the span beams with bolted connections atop pillars and subsequent installation of orthotropic plates, followed by waterproofing and asphalt laying.

Evgeny Vasiliev, Deputy Chair of Transport Infrastructure at the Aluminium Association, highlighted the substantial contribution made by the Aluminium Association and expert communities across the nation. This pioneering project necessitated exhaustive regulatory documentation and relied entirely on domestic research, materials, and technologies.

Throughout the bridge's construction, meticulous tests and trials focused on assessing dynamics, tension, fire resistance, wear resistance, and connection quality, ensuring its structural integrity and durability.

Leading scientific and production centers such as the Institute of Light Materials & Technologies (ILM&T), Moscow State University of Civil Engineering (NIU MGSU), and Research Center of Artificial Structures played pivotal roles in this groundbreaking project.

An exceptional advantage of aluminium structures lies in their minimal maintenance costs. These bridges forego regular anti-corrosion treatments and are easily transported to construction sites, reducing the need for expensive cranes or additional workforce due to their lightweight nature.

Irina Kazovskaya, Chair of the Aluminium Association, hailed aluminium as a potent material for bridge construction, underscoring its cost-effectiveness, environmental benefits, and aesthetic potential. She emphasized the material's ability to create innovative and futuristic constructions while ensuring a low cost of ownership and extended lifecycle.

Conclusion:

This landmark marks another stride in Russia's embrace of aluminium infrastructure, with the Aluminium Association actively fostering the development of transport infrastructure, indicating a growing trend in the construction of aluminium alloy bridges.
