Initial situation National road no. 7 (DN7) is one of the most important routes through theCarpathian Mountains, with heavy traffic. The Olt River runs parallel to the DN7with high mountains, directly next to the road. In winter and spring rockfallsoccur regularly. Also with unstable slopes, torrents and avalanches the risk ofaccidents was high.
This project was originally developed with five concrete canopies for rockfallprotection. Due to costs and other restrictions, a modern solution using hightensile steel wire was chosen. After further investigation, 23 dangerous areaswere found and had to be protected using two types of protection systems:active and passive.

As passive protection measures, AXI and RXI rockfall barriers with dynamiccapacity ranging from 500 to 3000 kJ were chosen for the following sectors:
1. km 198+523.72 - 198+571.00RXI-050
capacity: 500 kJlength: 20 mheight: 2.5 m
2. km 200+166 - 200+193RXI-200
capacity: 2.000 kJlength: 30 mheight: 6 m
3. km 200+207 - 200+219RXI-200
