Despite the fact that the initiative to build a modern road that will connect Istra with rest of Croatia dates back to 1968, Rogovići–Matulji section was opened much later, in the period from 1981 to 1998, and with only one carriageway. In 2008, simultaneously with the start of construction phase 2A on section from Kanfanar to Rogovići, preparations for construction of dual carriageway road on Rogovići–Matulji section also began.
With some deviations to improve design elements, preliminary solution of this 46.3km long section was designed in accordance with the existing carriageway to avoid devastation of residential buildings in the highway corridor wherever it was possible. Basic design speed is 100km/h, but because of mountain terrain and dense built–up area at some parts of the route it was reduced down to 80km/h. In retrospect, 9 junctions, 8 overpasses, 22 underpasses, 4 tunnels (3 previously constructed, and approx. 5660m long 2nd tube of 'Učka' tunnel designed on the north side of the existing one), 15 viaducts, 2 bridges, 8 pedestrian crossings and 2 B–type service areas are anticipated on Rogovići–Matulji section of highway A8.
Environmental impact study was made on basis of the preliminary solution, and in June 2010 it was submitted to the Ministry for environmental impact assessment. First advisory committee conference was held in November 2010, while the public discussion was carried out in the spring of 2011. Public viewings of the Study in Pazin, Opatija and Matulji had high attendance, with a large number of public complaints.
After consultations with local authority, investor and concessionaire officials, and taking into consideration the complaints from general public, preliminary design changes were made so that the highway can 'serve the public' in genuine sense of the word.
