Furthermore, the geological conditions surrounding the tunnel featured multiple areas of high compressive tectonic stress regimes, such as thrust faults, which necessitated greater levels of support to be installed in the tunnel than had been originally anticipated. Despite this, the boring process was completed eight months ahead of schedule. On 11 July 2009, a ceremony was held to mark the completion of the tunnels.
