The total length of the tunnel is 400m. The section shape of the main tunnel is round on the first 60.00m and semi-circular on the rest of its length. The support mechanism consists of two layers, the temporary support which is formed using forepoling tubes and 20cm sprayed concrete and the permanent lining which is formed by in-situ concrete.
The entrance and exit of the Tunnel are 19.00m and 25.00m long respectively and are constructed using the cut & cover method.
