Klokova

84% construction progress for Ionia Odos in August and record time for the excavation of Klokova tunnel

With the goal to have Ionia Odos motorway main line ready on March 2017 and the whole project fully completed a few months later on August 2017, construction works are progressing with high speeds. It is indicative that on the end of August, construction progress reached 84% and Klokova’s tunnel one of the most difficult and challenging projects of the motorway, was completed in the record time of 13 months, almost half a year earlier than planned. The final lining for both bores of the tunnel is expected to be completed by the end of November.
