The analysis of the gap pile Foundation of the bridge during construction the compressor station "Baydaratskaya" on the Yamal Peninsula, applying the technology of construction in the far North region, identified the cause of the destruction of pile Foundation (pile-rack). The analysis of deformation has been proven the urgency of the problem of deformation and destruction of the bridge piers on the border "water-air" in different traffic and climatic zones of Russia, including in the far North. Based on a practical analysis of the problem of the destruction we can draw the following important conclusions: - The destruction the bridge piers, piles in the area of "water-air", because of intense deformation and the requires external sources of protection. - Further study zone "water-air" is true in our time, and existing protection methods are not able to protect the structure from damage. - necessary practical research to identify ways to protect bridge piers in the area of "water-air". - necessary to control the state of the bridge's pillars after the construction of protective structures above the water level
