Performed work

 

Single-span metal bridge at km 2635+369.4 South-Caucasus railway

The bridge was built in 1899.

The material of the span – wrought iron.

During the exploitation the elements of the span have been seriously damaged and corroded. Meanwhile, rail load has significantly increased in comparison with the standards for more than 100 years ago.

Since April 2012 Kamurjshin CJSC is working to reconstruct stables and replace the old span by the new one.

The new span designed by modern rail loading C-14.

The work have been finished at the end of 2012.



 

Triple-span metal bridge at km 2626+816.6 South-Caucasus railway

The bridge was built in 1898.

The material of the span – wrought iron.

During the exploitation the elements of the span have been seriously damaged and corroded. Meanwhile, rail load has significantly increased in comparison with the standards for more than 100 years ago.

Since May 2012 Kamurjshin CJSC is working to reconstruct stables and replace the old span by the new one.

The new span designed by modern rail loading C-14.

The work have been finished at the end of 2012.
