 Despite being a shorter and a more direct route, those avenues are much more congested than the bypass at rush hours and they contain at-grade intersections and traffic lights at some of their junctions.The A3 is a partially tolled motorway based on the vehicle classification in Croatia.The westernmost section of the motorway, spanning the Bobovica interchange and the Bregana border crossing, is tolled at Bregana toll plaza using an open toll collection system; the motorway sections east of Ivanja Reka interchange are tolled using a closed toll collection system, integrated with the A5 motorway as the two connect at the Sredanci interchange, forming a unified toll collection system.
