The section ends close to the bridge on the âÂÂObrenovacâ interchange where next subsection, ObrenovacâÂÂUb, starts. The construction of this 17.6 kilometer-long section started in 2017 and was completed by the end of 2019 with main contractor China Communications Construction Company (CCCC).

It goes through flat terrain in valley of Kolubara and Ljig rivers, and after Ljig it enters hilly terrain.
The 40.3 kilometers-long section LjigâÂÂPreljina is first section of motorway A2 which was put into service. It was constructed from 2012 to 2016 by Azerbaijani company AzVirt. It starts near DiÃÂi which is few kilometers from Ljig, passes near Takovo where is exit 'Takovo' for Gornji Milanovac. This section ends on exit 'Preljina' near to ÃÂaÃÂak, where will be interchange with future A5 motorway.

Subsection PreljinaâÂÂPoà ¾ega was completed in 2025 (the Preljina-PakovraÃÂe section being inaugurated in 2022). It is 30.9 kilometers long and divided on 3 tranches: PreljinaâÂÂPrijevor, PrijevorâÂÂLuÃÂani and LuÃÂaniâÂÂPoà ¾ega. Commercial contract with Chinese company China Communications Construction Company (CCCC) worth 450 million euros was signed in 2017.

The most demanding part of the route is between Poà ¾ega and Duga Poljana, where 72 bridges with a total length of 35 km and 10 tunnels with a total length of 16.88 km are planned.
Five major interchanges are planned along the route:
The estimated cost of construction is around â¬1 billion. Works are expected to begin after the completion of the Preljina â Poà ¾ega section. Due to the challenging terrain, this section is considered one of the most complex in Serbia, with a large number of bridges and tunnels.
Exit list is shown just for sections between Belgrade and Poà ¾ega, because the detailed route for section Poà ¾egaâÂÂBoljare is currently unknown.
