sentences:  The expansion of the A8 was initially limited to the Kanfanar–Rogovići section because the remainder of the route required additional permits and consequently an extended preparation period.On 29 October 2011, the Kanfanar–Rogovići section was upgraded to motorway standards, including four traffic lanes, and the route's designation changed from B8 to A8 (as required by legislated standards).The construction performed along the section entailed deep and long cuts requiring temporary traffic stoppages due to explosive blasting.
