Tunnel Markovec is nearly 2.2 km long and it is the fourth longest among the 21 double bored tunnel in the country. It is build according to the highest standards and from security point it is extremely safe. In the pipe against Izola are fewer ventilators then in the pipe to Koper, because of bora wind.
PETRIČ is in this section of highway fitted modern removable door, which two people can open in less than 15 minutes, thus enabling the rapid conversion to the other opposite lane. The system is structured so that traffic diversion does not need any special tools. All that is required id that we release connection elements, remove the anchor and descend mounted castors. The door can be rotated in both directions by 60 degrees.
The entire project is worth 166.8 million. With the opening of the tunnel and highway could be provided new coastline between Koper and Izola.
