 The route between Bobovica and Ivanja Reka interchanges (inclusive) serves as a part of Zagreb bypass, and it is therefore not tolled. The A3 section of the bypass also comprises junctions to a number of other motorways: the A1 at the Lučko interchange, the A2 at the Jankomir interchange, the A11 motorway at the Jakuševec interchange, and the A4 at the Ivanja Reka interchange. Two interchanges east of Zagreb, Rugvica and Križ, have recently been built to fill in 20-kilometre (12 mi) gaps between the Ivanja Reka, Ivanić-Grad and Popovača interchanges, respectively. Even though the sections east of Rugvica are not parts of Zagreb bypass proper (they are tolled), the area has recently shown a rise in the population as it comprises several Zagreb suburbs and commuter towns. The consequent increase of commuter traffic volume, overall increase of the motorway transit traffic and plans for construction of a Sava River port in Rugvica warranted construction of the additional interchanges.
