The Road Infrastructure Agency has launched a public procurement for the development of a conceptual design for the Montana-Sofia expressway with a tunnel under the Petrohan Pass. The length of the section is 82 km and the design speed is 120km/h. The indicative value of the design contract is EUR 3.3 million. 

Until February 15 next year, offers will be accepted for the development of an extended conceptual design, complete engineering and geological studies and a detailed spatial plan for the expressway connecting the Montana bypass and the Sofia ring road. The task is to avoid crossing protected areas and to comply with all requirements in the Environmental Protection Act. The implementation deadline is 365 calendar days. The Sofia-Montana expressway with a tunnel under the Petrohan Pass is key to the national and the European transport network.
