R2 is an expressway () in Slovakia, which begins near TrenÃÂÃÂn and ends near Koà ¡ice. It passes Bánovce nad Bebravou, Prievidza, à ½iar nad Hronom, Zvolen, LuÃÂenec, Rimavská Sobota and Roà ¾à Âava. Sections between à ½iar nad Hronom and Zvolen are shared with R1 and R3. There is also a planned shared section between RáztoÃÂno and à ½iar nad Hronom with R3.
In view of the current intentions of the Ministry of Transport, the entire length of the expressway cannot be expected to be operational before 2050.
In October 2012, work began on an almost half-profile bypass around à ½iar nad Hronom, which was put into operation on 15 December 2014.
On 10 November 2015, a long section Pstruà ¡a - KrivÃ¡à  (in construction since 2013) was opened to traffic for a cost of EUR 177 million, after construction there was completed by Doprastav.
The section between Zvolen East and Pstruà ¡a has been put into operation in May 2017, receiving a EUR 44 million contribution from the European Union.
A section Mýtnaà- Lovinobaà Âa, TomÃ¡à ¡ovce was opened in late 2022.
Under construction since March 2020, the long section KrivÃ¡à  - Mýtna was financed from the state budget, and was carried out by a consortium of Doprastav, Strabag and Eurovia SK/CZ. The section opened to traffic on 20 November 2025, and features the longest highway bridge in Slovakia.
Several sections of the R2 are under planning or in development.
A further of the R2 is being built near Koà ¡ice, South - Koà ¡ické OÃ¾à ¡any, where the R2 will be shared with R4. Construction there began in March 2022 at a total cost of EUR 202 Million with VAT, cofinanced by the European Union.
