Due to the weak geology in the area, heavy rain and typhoons during the rainy season cause a lot of landslides and interruptions, and the curved road located right between the precipitous mountain and the seaside provokes a lot of accidents. In order to increase security and boost tourism in this area, especially from China, the Ministry of Transportation and Communications (MOTC) is building 38,4km of tunnels and bridges to replace the three most dangerous sectors of the highway.

The two tunnels have an overall length of approximately 13km, with the construction works being 7,94km and 4,66km each, with the corresponding costs for the two tunnels being TND 7.2bn and TND 9.208bn (USD 200M and USD 300M). The project started last year and is expected to be completed in 2018.

"We are proud that our equipment meets the requirements of Kung Sing Engineering Group for concrete spraying in tunnel construction" said Max Eckstein, International Sales Manager of the Putzmeister Underground Division.
