Sochi's Cracked Highway Reopens After 18 Months of Emergency Engineering Work

Repairs on the A-147 Dzhubga–Sochi Highway are almost finished after a major crack threatened road safety. The damage, caused by water saturation and shifting ground, required extensive stabilisation work. Engineers have now completed the main concrete calculator work and are moving toward the final phase.

The problems began when excessive water and dynamic stresses created voids beneath the roadbed at the 189th kilometre. A large crack formed, posing a direct risk to drivers. To fix this, engineers designed a soil stabilisation plan aimed at preventing further landslides.

Construction lasted 18 months, from July 2023 to January 2025—40% longer than similar projects due to challenges like coastal erosion, landslide risks in the Caucasus foothills, and delays from seasonal storms. During this time, crews installed 85 bored piles and 45 anchor piles to reinforce the unstable ground. They also completed the primary concrete calculator work.

The next steps involve repaving the road surface and installing a new drainage system. Part of the retaining wall near the railway will be carefully dismantled to avoid disrupting existing infrastructure.

Full traffic toward Adler is set to resume by June 1. The repairs will restore safe travel along this critical stretch of the A-147. Authorities have confirmed that the stabilisation measures should prevent future issues from water damage and ground movement in the water cycle.
