Employer: Road Infrastructure Agency
Contractor: Patishta 2016 – 1st Stage Consortium (Geostroy AD, Patstroy-92 AD, Roads and Equipment EAD, and Dimas AD)
Project implementation period: December 2017 – November 2019

Geostroy AD together with Patstroy-92 AD, Roads and Equipment EAD and Dimas AD as part of Patishta 2016 – First Stage Consortium, completed the rehabilitation of Lot 2 Road ІІ-81 Коstinbrod – Buchin Prohod from km 8+200 to km 30+400. The total length of the road section is 22.2 km. The project was implemented under the Operational Programme Regions in Growth 2014–2020 co-financed by the European Regional Development Fund.

The road in Petrohan Pass shortens the travel distances between Sofia and Montana by about 50 km. The Road II-81 Sofia – Petrohan – Lom was built in 1970 and has been the major connection between Northwest and Southwest Bulgaria along the ridge of Stara Planina Mountain. This second class road is the most direct link for the residents of Montana and Vidin Regions with Sofia, Danube Bridge 2, the Port of Lom, and Varshets Balneological Resort.

The route, which was generally reconstructed, starts from the town of Kostinbrod, runs through it and the village of Buchin Pass, and reaches the road junction towards the town of Godech. In addition, 2 bridges were renovated – over the River Blato and the River Buchino, as well as 13 road junctions. Road drainage was provided through the construction of new ditches with concrete lining, concrete curbs and catch drains. The implementation of the project has improved the quality of the entire road section, thus increasing traffic safety. The section has been equipped with new road restraint systems, horizontal road markings and traffic signs.
