In its current form, the Zagreb bypass has a small number of widely spaced interchanges. A proposal has been made in 2007 for a new interchange near Zaprešić. The current one prolongs the trip from Zaprešić to Zagreb via the bypass by .
The highway is currently four lanes wide throughout its entire length. It will be widened to six lanes between the Jankomir and Ivanja Reka interchanges due to the high traffic amounts. Experts presume that widening(s) of the highway will be good for the next 10 years. Afterwards, a new beltway will be built around Zagreb.
Due to the Medvednica mountain, Zagreb bypass is U-shaped, leaving the city without a northern bypass that would connect the A2 and A4 highways. A northern branch of the bypass (Sjeverna tangenta) is supposed to bridge the gap. It is supposed to connect the Zaprešić interchange with the Popovec interchange.

|Sveta Klara||City of Zagreb||A3, Većeslav Holjevac Avenue||Trumpet, in planning stages. Upon completion, it will supersede the Buzin exit. It is planned to be built in 2008.|
|5||19.1||Buzin||City of Zagreb||A3, D30 (Velikogorička Road), Germany Avenue||Currently an AB parclo. Due to congestion, its purpose as being an important link between Velika Gorica and Zagreb will be replaced by the new A11 highway and Jakuševec interchange. The current layout of Buzin interchange won't be in use anymore by 2008.|
|Jakuševec||City of Zagreb||A3, A11, Sarajevska Road||A cloverleaf. This interchange was a problematic one to build due to a connector highway from Sarajevska Road to the interchange itself. The connector highway had to pass either over or under a railway station near the interchange. The route under the station was chosen requiring a steep 6% grade on the connector highway.|
