The Omolion Tunnel ( Greek : Σήραγγα Ομόλιον) is located in Greece and is a motorway construction project under construction. Completion was originally planned for 2012. The construction costs were put at a total of 1.3 billion euros, the calculated construction time should take around 4.5 years.
location
The tunnel is located on the national road 1 (European route E75) Athens - Thessaloniki , in the section Tempe - Kato Aigani in the Thessaly region in central Greece. The road, which previously ran in a narrow river valley, is lined with 100-meter-high rock walls; the traffic planners considered it to be a highly urgent transport project due to frequent accidents caused by falling stones and boulders of enormous size. When another tragic accident occurred near Tempe in 2003 with 21 dead schoolchildren, the construction project that had been planned since 1963 and which had repeatedly fallen victim to austerity was approved by the Greek government. After completion of the tunnel structures, they will be part of Autobahn 1 .
Project data
The Omolion Tunnel consists of three tunnel structures: The Omolion Tunnel 1 begins on the outskirts of Tempe and is 1,900 meters long. It has two separate, parallel tunnel tubes that each accommodate a directional lane. After tunnel 1, the motorway passes a short side valley. This is followed by the Omolion Tunnel 2 with a total length of about 6,100 meters. The Rapsani motorway junction follows with a bridge required there. Here an access road from Kato Olympos meets the highway route. The last construction phase is the Omolion Tunnel 3 - it has a total length of 3200 meters. The entrance is at Panteleimon , the exit at Skotina . In the southern construction section of Tunnel 3, the use of blasting can be approved; in the northern construction section, mechanical jacking techniques must be used.
All tunnels have two tunnel tubes. The overall project ends near Kato Aigani within sight of the coast. The construction is particularly complicated and time-consuming due to geological anomalies in the mountain.
Framework
The tunnel builders have to follow a complicated, multi-curved route through the mountain. The rock is very loose and the use of blasting is very risky according to engineering geologists. In fact, in December 2009 there was a rockfall event in which a driver died on the busy road. Since an explosion took place at the same time, it was assumed that there was a direct connection. The project is being monitored and given technical advice by scientists from the University of Thessaloniki . Since Greece is in a zone of frequent earthquakes, special safety standards for the tunnel construction must be observed.
