The Krymsky Bridge was built in 1938 as the first fixed crossing over the River Moscow in the area, superseding the temporary floating bridges. Built on caisson foundations with a hanging deck of 262.5 m in length, 38.4 m in width and using approximately 10,000 t steel, the bridge has a unit weight distribution of approximately 1 t/1 m2, which is unique for a bridge like this.
Located on the Sadovoe Ring Road right next to Gorky Park, it is also one of the busiest bridges not only in Moscow, but in the whole Russia.
In 2001, during a capital reconstruction, the deck had to be repaired, pavement replaced along expansion joints and other works, with one of the limitations being keeping the traffic flowing.
This has required a special technical solution and construction approach.
To facilitate quick and as much as possible uninterrupted replacement, the TENSA-FLEX RC joints have been chosen, allowing to undertake replacement works lane-by-lane with minimum traffic disruption.
After successful reconstruction, the joints on the heavily trafficked bridge served whole 15 years, before some parts had to be replaced. Thanks to the already installed complete RC joint, this operational was much easier and quicker to perform, as these joints are specifically designed for such tasks.
mageba Russia had joined forces with the authority (GorMost) to provide a correct and efficient solution for the situation, letting the bridge continue its service for the capital.
