Total length of the tunnel is 3730 m. There is a multifunctional adit with total length of 3805 m running parallel to the tunnel. During 2003-2007 a thorough survey of the tunnel was conducted. According to the expert report, the tunnel had significant construction defects caused by mistakes during construction stage and poor quality of construction process.
