Reconstructed M-4 Don highway section (from 599 km to 633 km) was opened for traffic on November 26, 2011.
The startup ceremony was attended by Russian Transport Minister Igor Levitin, Voronezh regional Governor Alexei Gordeyev, Avtodor State Company CEO Sergei Kostin, and Donaerodorstroi Company Board Chairman Vladimir Kirsanov.
Donaerodorstroi was the general contractor of the reconstruction of the 33.949 km-long section of M-4 Don highway (from 599 km to 633 km) ordered by Avtodor State Company.
The reconstruction began in September 2009 and was accomplished in two stages.
The first stage included the expansion of the highway by a new two-lane traffic way in the Moscow – Rostov-on-Don direction.
The second stage was the reconstruction of the existing highway (traffic bypassed by the newly built way during the reconstruction period) which resulted in a two-lane way in the Rostov-on-Don – Moscow direction.
The reconstruction of the M-4 Don highway section running from 599 km to 633 km resulted in a four-lane first-category highway with divided flows of oncoming traffic. The rated traffic speed comprises 120 kilometers per hour.
The reconstruction became necessary as technical parameters of the section did not correspond to existing and future traffic density and did not comply with requirements to highways that ensure inter-regional road communications.
The federal highway M-4 Don from Moscow to Novorossiisk is the main vertical axis of the Russian road network. It unites central and northern regions of the European part of the country with North Caucasus, the Black Sea coast, and the seaport of Novorossiisk.
In Voronezh region the average annual traffic density on the M-4 Don highway comprises 30 thousand kilometers a day. Cargo traffic exceeds 12 million tons and passenger flow – 16 million people a year.
The startup of the reconstructed section will accelerate traffic flow and decrease transportation and maintenance costs, the number of accidents and the negative impact on the environment, and will give additional impulse to the social and economic development of the region.
In 2012-2013 the 599 km – 633 km section will become a toll road.
