Road Workers Install Span Constructions over the Don at the New Aksay Bypass

“Russian Highways” State Company continues its largest Aksay Bypass infrastructural project.

At the new section of M-4 "Don" Highway 35.5 km long, road workers deal with the top dressing made of coarse-grained solid bitumen-concrete. Bitumen-concrete plant has the capacity of 250–260 tons per hour. Thus, asphalt spreaders can finish 900 to 950 meters per day.

The bridge will cross the Don River. On the right bank, support structures are 90 % ready. Currently, workers install spans, construct a temporary support and launch over-water length of the span structure. Supports are in progress on the left bank.

Now, the alluvial of the Don River is replaced, with layer-by-layer filling, replacement of soil with sand, reinforcement installation, and mound filling. According to the project, about 7 million cubic meters of weak alluvial soil will be replaced. Almost 50 % of works are finalized, with 3.5 million cubic meters of soil being removed.

The new four-lane high-speed section of IA category highway will include three transport interchanges, eight cross-overs and five bridges, and two pedestrian overpasses at the crossing with the current M-4 "Don" Highway and entrance to Novocherkassk and Aksay – Bolshoy Log – Novocherkassk Road.

According to the project, the new highway section is to be commissioned in 2024, yet the road workers already proceed ahead of schedule and intend to open the bypass for traffic in 2023. Aksay bypass will become a part of the Rostov Road Ring, which will generally greatly redirect trucks from passing the southern capital, increase the speed of transit carriage and open new possibilities to develop the transport and economical connections of the region.

Apart from the works at a new M-4 "Don" section, 17.1 km of the highway, from Dorozhny settlement to 1,091+600 km, are being reconstructed. The first repaired section of the Aksay bypass from Novopersianovka to the junction towards Novocherkassk was commissioned in December 2020.
