The section runs through the Turtkul, Ellikkala and Beruniy districts, on the Guzar–Bukhara–Nukus–Beyneu corridor that links western Uzbekistan with Kazakhstan. It is part of the CAREC Road Corridor 2 Resilience and Modernization Project, for which the ADB approved a US$233.1 million sovereign loan in August 2025. The total project cost is US$293.7 million, with the Government of Uzbekistan contributing US$60.6 million.
Under the programme, about 87 kilometres of the A380 will be rebuilt or upgraded: a new 75-kilometre, four-lane bypass serving Turtkul, Ellikkala and Beruniy, plus reconstruction of a 12-kilometre stretch of the existing carriageway. Design provisions include cement concrete pavement, elevated embankments and improved drainage intended to withstand extreme weather. The ADB is also supporting intelligent transport systems and weigh-in-motion technology for axle-load enforcement, along with five rest and service areas that will include electric vehicle charging.
The A380 is a strategic link in CAREC Corridor 2 and one of the main road connections between Uzbekistan and Kazakhstan. Uzbek authorities expect transit traffic on the corridor to rise 1.5 times once the section is complete, and cargo entering Turtkul to reach the Kazakh border in 10 hours instead of a full day. The works follow an earlier ADB-financed upgrade of a 240-kilometre section through Kungrad. Uzbekistan has received about US$14.3 billion in ADB loans, grants and technical assistance since joining the bank in 1995.
