Belgrade Bypass (A1, E70/E75)
The A1 motorway ring road west and south of Belgrade, from Batajnica through the A3 junction at Dobanovci, the Surčin interchange with the A2 and the Ostružnica bridge over the Sava, to Bubanj Potok. Sector A opened in 2012. Sector B, 37.2 km, was built in stages from 2005; its last 19.5 km (sectors 4–6 in the ministry's numbering, built by PowerChina) have been in traffic since 29 June 2023. Sector C (Bubanj Potok – Pančevo, about 31 km) is not built and has no fixed route, so it is not drawn here. No outturn cost is recorded: the ministry gives a contract value for sectors 4–6 only.

| Sections | Status | Length | Timeline | Cost | Funding | Contractors | Contract terms |
|---|---|---|---|---|---|---|---|
| Sector A: Batajnica – Dobanovci English Wikipedia gives 10.1 km and an opening in 2012 (year only). The drawn alignment between the Batajnica interchange and the A3 crossing at Dobanovci measures about 7.9 km, so the recorded length may include approaches beyond the cut points; the sourced figure is kept. | Opened | 10 km |

| Sector B, sections 1–3: Dobanovci – Ostružnica Dobanovci – Surčin (7.8 km), Surčin – Ostružnica bridge (4.9 km) and Ostružnica bridge – Ostružnica (4.1 km, with the 1,950 m Ostružnica bridge), summed from English Wikipedia. The right carriageway opened in 2005 on all three; the left opened in 2016 on the first two and in June 2020 on the third. The Ostružnica interchange is taken as the start of the ministry's sector 4. The drawn length is 14.5 km. | Opened | 17 km |

| Sector B, sector 4: Ostružnica – Orlovača Ministry sector 4, from the Ostružnica bridge to the Orlovača interchange, with the Lipak and Železnik tunnels. The ministry gives the whole 19.5 km (sectors 4–6) as in traffic from 29 June 2023, and a contract value of CNY 2.59 billion for it, not split by sector. The ministry's project start of 24 December 2018 is recorded on sector 6 only (see there). English Wikipedia dates the earlier right carriageway to 2008 and the left to April 2021 (7.7 km on its cut). | Opened | 7 km |

| Sector B, sector 5: Orlovača – Straževica tunnel Ministry sector 5, from the Orlovača interchange to the Straževica tunnel (772 m on English Wikipedia; the lot is drawn to its west portal). The ministry gives the whole 19.5 km (sectors 4–6) as in traffic from 29 June 2023; the contract value is stated for the three sectors together (see sector 4). English Wikipedia dates the earlier right carriageway to 2012 and the left to 15 June 2022. | Opened | 3 km |

| Sector B, sector 6: Straževica tunnel – Bubanj Potok Ministry sector 6, from the Straževica tunnel to Bubanj Potok, with the Avala interchange. The ministry gives the whole 19.5 km (sectors 4–6) as in traffic from 29 June 2023; the contract value is stated for the three sectors together (see sector 4). The ministry gives 24 December 2018 as the project start; this is the one sector built as a full profile under that contract, so it is recorded as the construction start here and not on sectors 4 and 5, whose right carriageways were built earlier. English Wikipedia gives 9.74 km and an opening on 28 June 2023. The drawn length is 8.2 km, ending where the mapped bypass meets the A1 at Bubanj Potok. | Opened | 10 km |
