Preparations for the construction of the first section of the motorway in Slovenia have been going on for five years, and on 29 December 1972 the 32 km long motorway section between Vrhnika and Postojna was handed over to traffic. With this project, Slovenia or the former Yugoslavia joins twenty European countries that already have motorways. Workers from all Yugoslav republics are taking part in the construction, mostly from Macedonia, from where they were driven by the desire for higher earnings. Construction divided into three subsections (Vrhnika-Logatec, Logatec-Unec and Unec-Postojna).

On the Vrhnika-Logatec section, the initial part near Vrhnika causes problems for workers due to the unfavorable geological base. Like the builders of the Southern Railway, the builders of the motorway section have problems with the swampy soil of the Ljubljana Marshes. With the preloading process, they cause forced subsidence of the ground, thus preventing subsequent deformations of the road. Five overpasses, four underpasses and the Verd viaduct (630 m) are being built on the section. Most of the headaches and related delays cause contractors to break through the Štampet Bridge.

Interesting:

All facilities on the bog soil are built on piles, which due to the variability of the terrain reach between 15 and 40 meters in depth.
