The construction of the A8 motorway (and the Istrian Y as a whole) has its origin in 1968, when the Croatian Parliament endorsed a petition by Istrian legislators for the construction of a modern road between the peninsula and the rest of Croatia. Subsequently, Istrian municipalities started a public bond to fund the construction of the Učka Tunnel. This construction happened between 1976 and 1981, including the construction of a route section between Matulji and Lupoglav.
