The Belgrade Bypass connects the branch of the Corridor Xb, E-75 (border with Hungry, Horgoš- Novi Sad-Belgrade) to the Corridor X, E-70 (Border with Croatia Batrovci-Belgrade), I B Category state road No. 26 and Route 4, E-763 (Belgrade-Požega-border with Monte Negro Boljare), and again to the segment of the Corridor X, E-75 (Belgrade - Niš – Preševo – Border with Republic of North Macedonia).

Due to the construction of the Belgrade Bypass traffic is diverted from highly frequented core urban road networks of Belgrade to the Belgrade Bypass, which contributes to reducing of travel time for transit traffic flows, reducing number of traffic accidents, cost of vehicle exploitation, toxic gases and noise in the narrow city area.

Belgrade Bypass comprises the following sections:

Section A: Batajnica-Dobanovci – works on the route and on Dobanovci and Batajnica interchange are completed.

Section B: Dobanovci – Bubanj potok

It consists of 6 sectors, as follows:

• sectors B1-B3: Dobanovci – bridge on the Sava at Ostružnica: completed works
• bridge on the Sava at Ostružnica: completed works
• sector B4: completed right highway lane (phase I), left highway lane (phase II), intersections “Orlovača” and „Petlovo Brdo“.
• sector B5: completed right highway lane from the interchange “Orlovača” to the exit from the tunnel Straževica (phase I), completed left highway lane (phase II), 3 bridges and left tube of the tunnel Straževica
• sector B6: tunnel Straževica – interchange “Bubanj Potok”, works on the construction of the left and the right highway lane are completed.

Section C: Bubanj potok - Pančevo (E-70) – upcoming works

TECHNICAL CHARACTERISTICS OF THE SECTION:

The total length of the Bypass section from Dobanovci to Bubanj potok is 47.4 km and is designed with a calculated speed of 120 km/h.

The road profile consists of:

• driving lane ............................ 4 x 3.75 m
• emergency lane ...................... 2 h 3.00 m
• marginal strip .................... 2 h 2 x 0.50 m
• median strip .............................. 4.00 m
• shoulder ................................... 2 h 1.50 m

Total ......................................................30.00 m

Minimum applied horizontal curve radius is 1,000 m, and maximum gradient is 3.8%.

NODES AND INTERCHANGES:

Five nods are designed on this section: two of the being at section ends and three in the middle part of the section.

Solutions for layout and elevation of the basic alignment are specified in such a manner that the construction of other interchanges will also be possible in the future, provided that justified traffic reasons substantiate such an action.

BRIDGES:

There are 41 bridge localities with 79 structures on the section Dobanovci - Bubanj potok.

The biggest bridge is the one over the Sava River near Ostružnica, consisting of three structures in total length of 1,965 m (steel structures over the river and approach concrete frameworks on both banks).

All other bridges are concrete, whereas five bridges are distinguished by size: “Sveta Petka“ (408 m), “Železnička reka“ (406 m), “Kijevski potok“ (571 m), “Topčiderska dolina“ (597 m) and “Bridge over the railway line”, 430 m).

TUNNELS:

Four tunnels are designed on this route and those are the following: “Lipak” (partially under the plateau of the railway station Ostružnica, length 665 m), “Železnik” (699 m) and “Beli potok” (under Avala road, 360 m) with two tunnel tubes, and the “Straževica” Tunnel (under Resnik, 745 m) with two separate tubes.
